How Skin Cancer Can Spread – The Symptoms

Skin cancer is by far the most common type of cancer and each year there are more new cases of skin cancer than the combined cases of breast, prostate, lung and colon cancer. This translates to one in five Americans developing skin cancer over their lifetime. Following basal cell carcinoma, squamous cell carcinoma is the second most common type of skin cancer. According to the American Cancer Society, about 5.4 million basal and squamous cell skin cancers are diagnosed each year in America. Squamous cell carcinoma accounts for ~20% of these cases.

Who is at risk for squamous cell carcinoma?Skin cancer occurs at every age in persons of every ethnicity and gender. Risk for squamous cell carcinoma increases with the following factors:

  • Ultraviolet light exposure from the sun and indoor tanning
  • History of sunburns, especially during childhood
  • Lighter skin color equating to increased sensitivity to ultraviolet light. Although less common overall in darker skin types, squamous cell carcinoma accounts for a larger proportion of skin cancers in this population.
  • Incidence increases with age
  • Male gender men are especially at risk after age 60, whereas women account for more skin cancers in those under age 40
  • Personal or family history of skin cancer
  • Human Papillomavirus Virus infection

This Is Why A New Though Tiny Spot Or Speck Should Not Be Ignored Even If It Looks Normal

Melanoma

Ultimately I believe genetics will help determine the behavior of these, but until we have that data we have to look at patterns, explains Dr. Gordon.

In general, survival rate of melanomas depends on depth of the cancer.

This depth is determined by a dermapathologist who examines a biopsy of the suspicious spot, which includes a surrounding margin of skin also taken out, under a microscope.

The rule of thumb is that the height of the melanoma above the surface of the skin is equal to its depth below the skin surface.

Dr. Gordon explains, In general, smaller lesions the thinner they are and the better outcomes people have.

Some melanomas will grow in a spreading pattern on the skin , but some will grow in a deep pattern that are more aggressive .

There is no easy way to decipher the spread of melanoma until it is biopsied and sometimes until further tests are performed.

Dr. Gordons interests include medical dermatology, particularly the treatment and prevention of melanoma and other skin cancers in athletes. For 2016, 2017 and 2018 Texas Monthly Magazine selected her as one of the Texas Super Doctors Rising Stars.

Staging For Basal Cell And Squamous Cell Carcinoma

Basal cell and squamous cell carcinoma usually do not spread to other parts of the body. On rare occasions, a persons lymph node may be removed to find out if the cancer has spread, which is called metastasis. Lymph nodes are bean-shaped organs that help fight infection. The doctor may recommend other tests to determine the extent of the disease, including blood tests, chest x-rays, and imaging scans of the lymph nodes and nerves, liver, bones, and brain, but this is uncommon.

What Is The Prognosis Of Squamous Cell Carcinoma Of Oral Cavity

  • In general, Squamous Cell Carcinoma of Oral Cavity is an aggressive form of cancer. If metastasis is observed, then the prognosis is guarded or unpredictable
  • Tumors in their early stage with complete excisional treatment typically have good prognosis
  • In cases of metastasis, its prognosis depends upon a set of several factors that include:
  • Stage of tumor: With lower-stage tumors, when the tumor is confined to site of origin, the prognosis is usually excellent with appropriate therapy. In higher-stage tumors, such as tumors with metastasis, the prognosis is poor
  • The surgical respectability of the tumor
  • Overall health of the individual: Individuals with overall excellent health have better prognosis compared to those with poor health
  • Age of the individual: Older individuals generally have poorer prognosis than younger individuals
  • Whether the tumor is occurring for the first time, or is a recurrent tumor. Recurring tumors have a poorer prognosis compared to tumors that do not recur
  • Response to treatment: Tumors that respond to treatment have better prognosis compared to tumors that do not respond so well to treatment

Doctors Want To Give Their Cancer Patients Every Chance But Are They Pushing Off Hard Talks Too Long

Endometrial cancer how fast does it spread

His team then gave mice implanted with human melanomas a weeklong regimen of an MCT1 blocker, AstraZenecas investigational AZD3965. Result: The animals had fewer melanoma cells in the blood and fewer metastases.

Inhibiting MCT1 doesnt have much effect on the primary tumor or on established metastases, Morrison said. But for cells in between, it can prevent metastasis and, at least in the mice, extend survival.

Although AstraZenecas MCT1 inhibitor is being tested in an early-stage clinical trial, the participants have solid tumors that have already metastasized. Morrison thinks thats too late: Oxidative stress kills cancer cells in the bloodstream, not once theyve reached their destination. If blocking MCT1 and thereby exposing tumor cells to oxidative stress in the bloodstream has any benefit, he said, it will be around stage 3, when cancer cells have reached the bloodstream and lymph nodes but not beyond.

Our prediction is that blocking MCT1 wont have much activity against stage 4 melanoma, but if used as an adjuvant therapy in stage 3, it might decrease the percentage of patients who progress to stage 4, Morrison said.

His discovery might extend beyond melanoma. Lung and pancreatic tumor cells also use MCT1 to grab lactate from the bloodstream, presumably enabling those cancers, too, to metastasize.

Stem Cell Or Bone Marrow Transplant

A stem cell transplant, sometimes called bone marrow transplant, replaces damaged blood-forming cells with healthy ones. The procedure takes place following large-dose chemotherapy or radiation therapy to kill cancer cells and to stop your stem cells from producing cancerous cells.

Stem cell transplants can be used for several types of cancer, including multiple myeloma and some kinds of leukemia.

What Causes Skin Cancer

Almost all skin cancers in Australia are caused by too much exposure to UV radiation. This is the part of sunlight that causes tanning, sunburn and skin damage over time. UV radiation also comes from non-natural sources such as sun beds .

While anyone can get skin cancer, it is more common if you are older. The risk is also higher if you have:

  • previously had skin cancer or have family history of skin cancer
  • fair or freckled skin, particularly if it burns easily or doesnt tan
  • red or fair hair and light-coloured eyes
  • a weakened immune system
  • sunspots or irregular moles on your body
  • worked, played sport or spent leisure time in the sun
  • actively tan or use sun beds

If you have olive or dark skin, your skin produces more melanin, which protects against UV radiation. However, its still possible for you to develop skin cancer.

Symptoms Of Metastatic Melanoma Other Than A Mole

Other symptoms of this type of cancer may not appear until a later stage, when the melanoma has metastasized to another area of the body. Metastatic melanoma most often spreads to the lymph nodes, brain, bones, liver or lungs, and the additional symptoms experienced at this late stage will depend on where the melanoma has spread. For example:

  • Lungs A persistent cough or shortness of breath
  • Brain Headaches or seizures

Rare type of skin cancer grows fast, spreads quickly

A mole developing the following characteristics at a fast pace, within days or weeks could show melanoma:

  • Asymmetry, or both sides of the hole looking different
  • Border or moles with blurry or jagged edges
  • Color, or moles darkening, loosing color, or spotting multiple colors such as blue, red, white, pink, purple or gray
  • Diameter, or a mole larger than 1/4 inch in diameter
  • Elevation, or a mole raised above the skin and with a rough surface.

The bleeding or itching of such moles reinforces the possibility of melanoma. Apart from moles, speedy development of a scaly or crusted growth on the skin could also show spread of melanoma.

Don’t Miss: Who Can Diagnose Skin Cancer

How Fast Does Melanoma Spread

Melanoma is a deadly form of skin cancer because of its ability to metastasize to local lymph nodes and other organs. It is estimated that melanoma kills, on average, over 10,000 people in the United States every year.

The first sign of flat melanoma is usually a new spot or an existing mole or freckle that changes in appearance. Some changes can include:

  • A spot that has grown in size
  • A spot where the edges are looking irregular versus smooth and even
  • A spot that has a range of colors such as brown, black, blue, red, white or light gray.
  • A spot that has become itchy or is bleeding

According to Dr. Andrew Duncanson, board-certified dermatologist at Forefront Dermatology, It is important to know that melanoma can appear on areas of the skin not normally exposed to the sun such as under the arm, chest, and buttocks. It can also appear in areas that you are not able to see easily on your own including the ears, scalp, back of legs, and bottom of feet. I always recommend to my patients to look for the ugly duckling spot the new spot that doesnt look like any others. Additionally, ask a family member to look over the hard to see areas monthly, while also getting an annual skin cancer exam by a board-certified dermatologist to detect skin cancer early.

Basal Cell Carcinoma Stages

There are certain features that are considered to make the cancer at higher risk for spreading or recurrence, and these may also be used to stage basal cell carcinomas. These include:

  • Greater than 2 mm in thickness
  • Invasion into the lower dermis or subcutis layers of the skin
  • Invasion into the tiny nerves in the skin
  • Location on the ear or on a hair-bearing lip

After the TNM components and risk factors have been established, the cancer is given a stage. For basal cell carcinoma staging, the factors are grouped and labeled 0 to 4. The characteristics and stages of basal cell carcinoma are:

Stage 0: Also called carcinoma in situ, cancer discovered in this stage is only present in the epidermis and has not spread deeper to the dermis.

Stage 1 basal cell carcinoma: The cancer is less than 2 centimeters, about 4/5 of an inch across, has not spread to nearby lymph nodes or organs, and has one or fewer high-risk features.

Stage 2 basal cell carcinoma: The cancer is larger than 2 centimeters across, and has not spread to nearby organs or lymph nodes, or a tumor of any size with 2 or more high-risk features.

Stage 3 basal cell carcinoma: The cancer has spread into facial bones or 1 nearby lymph node, but not to other organs.

Stage 4 basal cell carcinoma: The cancer can be any size and has spread to 1 or more lymph nodes which are larger than 3 cm and may have spread to bones or other organs in the body.

Early Detection Prevents Melanoma From Spreading

While there are still many mysteries when it comes to why and how melanoma develops, it is certain that the sooner melanoma is discovered, the lower the chances of it spreading and becoming deadly. Thats why its essential to perform regular skin checks and know the symptoms of melanoma so you can catch it early.

How Is Squamous Cell Carcinoma Of The Skin Treated When It Spreads

How Fast Does Skin Cancer Grow

When this cancer spreads beyond the skin, it travels to the lymph nodes or other organs. Once it spreads, a patient has advanced cancer.

If youâve been diagnosed with advanced SCC, you will be cared for by a team of medical professionals. This team will include oncologists . Your treatment plan may include one or more of the following:

Surgery: When surgery can remove the cancer and youre healthy enough to have surgery, this is often the preferred treatment. After surgery, another treatment, such as radiation therapy or chemotherapy, is often given. Adding another treatment helps to kill cancer cells.

Radiation therapy: Radiation can target cancer cells in the skin, lymph nodes, or other areas of the body. When a patient has advanced SCC, radiation therapy is often used along with another treatment.

Immunotherapy: This type of treatment helps strengthen your immune system so that it can fight the cancer. Drugs called immunotherapy medications are given for this purpose.

The U.S. Food and Drug Administration has approved one immunotherapy medication for the treatment of advanced SCC of the skin. Its called cemiplimab-rwlc.

In the clinical trials that led the FDA to approve cemiplimab-rwlc, about half the patients who had advanced SCC of the skin had their tumors shrink. In many patients who had tumor shrinkage, the shrinking lasted 6 months or longer. A few patients had their tumors disappear completely.

Immunotherapy

Pembrolizumab is also given by IV infusion.

Where Else Does Melanoma Spread To

When melanoma advances to stage 3, it means the tumor has spread to the lymph nodes or the skin around the primary tumor and lymph nodes. In stage 4, the cancer has moved to other areas far beyond the lymph nodes, like your internal organs. The most common places melanoma spreads to are the:

  • lungs
  • brain
  • stomach, or abdomen

These growths will cause different symptoms, depending on which areas it has spread to. For example, you may feel breathless or constantly cough if the cancer has spread to your lungs. Or you may have a long-term headache that wont go away if it has spread to your brain. Sometimes the symptoms for stage 4 melanoma may not appear for many years after the original tumor was removed.

Talk to your doctor if youre feeling new pains and aches or symptoms. Theyll be able to help diagnose the cause and recommend treatment options.

Squamous Cell Carcinoma Early Stages

The second most common form of cancer in the skin is squamous cell carcinoma. At first, cancer cells appear as flat patches in the skin, often with a rough, scaly, reddish, or brown surface. These abnormal cells slowly grow in sun-exposed areas. Without proper treatment, squamous cell carcinoma can become life-threatening once it has spread and damaged healthy tissue and organs.

Spread Through The Bloodstream

Cancer cells can go into small blood vessels and then get into the bloodstream. They are called circulating tumour cells .

Researchers are looking at using circulating tumour cells to diagnose cancer instead of a tissue sample . And at whether they can test circulating cancer cells to predict which treatments will work better. They are also looking to detect circulating tumour DNA to help diagnose cancer and monitor treatment.

The circulating blood sweeps the cancer cells along until they get stuck somewhere. Often they get stuck in a very small blood vessel such as a capillary.

Then the cancer cell must move through the wall of the capillary and into the tissue of the organ close by. The cell can multiply to form a new tumour if:

  • the conditions are right for it to grow
  • it has the nutrients that it needs.

This is quite a complicated process and most cancer cells don’t survive it. Of the many thousands of cancer cells that reach the bloodstream, only a few survive to form a secondary cancer.

The white blood cells in our immune system find and kill some cancer cells. Others cancer cells might die because they get battered around by the fast flowing blood.

Cancer cells in the circulation may try to stick to platelets to form clumps to give themselves some protection. Platelets are blood cells that help the blood to clot. This could also help the cancer cells to move into the surrounding tissues.

Treating Stage 1 To 2 Melanoma

How does melanoma spread to the brain?

Treating stage 1 melanoma involves surgery to remove the melanoma and a small area of skin around it. This is known as surgical excision.

Surgical excision is usually done using local anaesthetic, which means you’ll be awake, but the area around the melanoma will be numbed, so you will not feel pain. In some cases, general anaesthetic is used, which means you’ll be unconscious during the procedure.

If a surgical excision is likely to leave a significant scar, it may be done in combination with a skin graft. However, skin flaps are now more commonly used because the scars are usually less noticeable than those resulting from a skin graft.

Read more about flap surgery.

In most cases, once the melanoma has been removed there’s little possibility of it returning and no further treatment should be needed. Most people are monitored for 1 to 5 years and are then discharged with no further problems.

Taking Care Of Yourself

Hearing that your cancer has spread is scary, but a lot of research is underway to find new treatments. And there are treatments available to try to stop the disease from spreading, so you can live longer.

It’s important to have support and to talk about your fears and feelings, too. Your doctor can help you find a cancer support group.

These tips may help you feel better during melanoma treatment:

  • If you lose your appetite, eat small amounts of food every 2 to 3 hours instead of bigger meals. A dietitian can give you other tips on nutrition and eating during your cancer treatment. Ask your doctor for a referral.
  • Exercise can help you feel better overall and fight fatigue. But listen to your body, and balance rest and activity.
  • Get the kind of emotional support that’s right for you. It could be from family, friends, your cancer support group, or a religious group.
