How The Government Of Canada Protects You
The Public Health Agency of Canada monitors cancer in Canada. PHAC identifies trends and risk factors for cancer, develops programs to reduce cancer risks, and researches to evaluate risks from the environment and human behaviours. Health Canada also promotes public awareness about sun safety and the harmful effects of UV rays.
What Is The Prognosis For Skin Cancer
Although the number of skin cancers in the United States continues to rise, more and more skin cancers are being caught earlier, when they are easier to treat. Thus, illness and death rates have decreased.
When treated properly, the cure rate for both basal cell carcinoma and squamous cell carcinoma approaches 95%. The remaining cancers recur at some point after treatment.
- Recurrences of these cancers are almost always local , but they often cause significant tissue destruction.
- Less than 1% of squamous cell carcinomas will eventually spread elsewhere in the body and turn into dangerous cancer.
In most cases, the outcome of malignant melanoma depends on the thickness of the tumor at the time of treatment.
- Thin lesions are almost always cured by simple surgery alone.
- Thicker tumors, which usually have been present for some time but have gone undetected, may spread to other organs. Surgery removes the tumor and any local spread, but it cannot remove distant metastasis. Other therapies, new targeted agents or older approaches such as radiation therapy or chemotherapy, are used to treat the metastatic tumors.
- Malignant melanoma causes more than 75% of deaths from skin cancer.
- Of the approximately 70,000 malignant melanomas diagnosed in the United States in 2007, the vast majority were cured. Still, thousands of people die of melanoma each year.
Recommendations For Prevention And Early Detection Of Skin Cancer In People Of Color
Prevention is better than cure and more than 90% of skin cancers are preventable . Because many people of color believe that they are not at risk of skin cancer, education through media and doctors offices is extremely important. People of color should perform regular self examination of their skin from head to the toe carefully every month. There are various types of skin tumors, many are benign which include moles , warts and lipomas etc that can develop from different types of skin cells . However, unusual moles, sores, lumps, blemishes, markings or changes in the way an area of the skin looks or feels may be a sign of melanoma or another type of skin cancer or a warning that it might occur. Know your ABCDEs can be a good guide for people of color to detect melanoma at an early stage .

Risk Factors And Causes Of Skin Cancer
Despite the fact that high melanin content confers better photo protection, significant photo damage in the form of epidermal atypia and atrophy, dermal collagen and elastin damage and pigmentary disorders can cause skin cancer which could be fatal due to delay in detection in skin of color . Skin cancer is skin growth with varying degrees of malignancy . It is not yet very clear why skin cancer incidence has grown so dramatically over the past decades but the reason is likely to be multi factorial which includes increased UV exposure, environmental, hereditary risk factors and improved surveillance and earlier recognition . In addition, genetic polymorphisms also modulate the susceptibility to skin cancer .
Organ transplant receivers especially kidney and HIV patients have an increased frequency of skin cancers . Some treatments, including radiation therapy, phototherapy, psoralen and long-wave ultraviolet radiation can also predispose to skin malignancies . Viral infections such as the human papilloma virus can cause cancer. Patients with familial genetic patterns are vulnerable to particular types of skin cancers . Certain drugs, from common antibiotics to heart medications, can increase the skins sensitivity to sunlight, causing the skin to burn in less time and may increase the incidence of skin cancer .

Biological Therapies And Melanoma
Biological therapies are treatments using substances made naturally by the body. Some of these treatments are called immunotherapy because they help the immune system fight the cancer, or they occur naturally as part of the immune system.
There are many biological therapies being researched and trialled, which in the future may help treat people with melanoma. They include monoclonal antibodies and vaccine therapy.
Skin Cancer Of The Head And Neck Treatment
Many early-stage small basal cell cancers or squamous cell cancers can be removed by Mohs surgery, a technique that spares normal tissue through repeated intraoperative margin testing, removing only the cancer and leaving adjacent normal tissue. Tumors with nerve involvement, lymph node involvement or of a large size are not suitable for Mohs surgery. They require a multimodality approach to treatment, with formal surgical resection and adjuvant radiation or chemotherapy.
Melanoma is more likely to spread, and aggressive surgical resection with wide margins is required, in addition to radiation and/or chemotherapy.

Leaving Basal Cell Carcinoma Untreated
Basal cell carcinoma is a slow growing cancer, but this doesnt mean it can be ignored. This is the least dangerous form of skin cancer and rarely spreads to other internal parts of the body. While death is a rare consequence there is the potential for disfigurement. Over time basal cell carcinoma can expand and cause ulcers and damage the skin and tissues.
Any damage could be permanent and have an impact on the way you look. Depending on how long the basal cell carcinoma has been present, radiotherapy may be required. This is the most common form of skin cancer and is often found on the face. You may notice a small lump which is shiny or pearl like and this is a sign you should get checked. This type of cancer generally does not cause any pain.
Complementary And Alternative Treatments
Its common for people with cancer to seek out complementary or alternative treatments. When used alongside your conventional cancer treatment, some of these therapies can make you feel better and improve your quality of life. Others may not be so helpful and in some cases may be harmful. It is important to tell all your healthcare professionals about any complementary medicines you are taking. Never stop taking your conventional treatment without consulting your doctor first.All treatments can have side effects. These days, new treatments are available that can help to make many side effects much less severe than they were in the past.

Ask The Expert: Why Are More Men Dying Of Skin Cancer
Q: Recent reports show that male deaths due to skin cancer are increasing around the world. What do you think is going on, and how can we help men fare better?
Yes, skin cancer deaths in men are on the rise both overseas and here. We know that in the U.S., men who are 49 and under have a higher probability of developing melanoma than any other cancer, and from ages 15 to 39, American men are 55 percent more likely to die of melanoma than women in the same age group. The majority of people in the U.S. diagnosed with melanoma are white men over age 55.
If caught early, melanoma and most skin cancers have a high cure rate. But that is the tricky thing: Men tend to come in for skin checks less frequently than women, and when they do, it may be after a long lag between seeing a suspicious spot and actually coming into the office. The difference can be deadly. And with men, melanoma is more likely to occur on the back of the torso or on the scalp, areas that they cant easily see by themselves. In many cases, it can require a partner spotting it and urging them to see a dermatologist to get it checked out.
Every summer I go to my kids summer camp to talk to the staff about sun safety, too. I hope the generation growing up now is in a better position, so we dont have boys becoming men who have no clue about the skin cancer risks from sun exposure and about what it takes to stay safe.

Skin Cancer: Quick Facts From The Surgeon General
Skin cancer is a serious public health concern.
Every year, there are more than 63,000 new cases of melanoma, the deadliest form of skin cancer, resulting in nearly 9,000 deaths.
Skin cancer is the most commonly diagnosed cancer in the United States, with 5 MILLION PEOPLE treated each year.
Treatment for skin cancer costs $8.1 BILLION each year in the United States.
Anyone can get skin cancer. Although those with lighter skin are at higher risk of getting skin cancer, people with darker skin may often be diagnosed with skin cancer at a later stage, making it difficult to treat.
Most skin cancers can be preventedbut we arent doing enough.
More than 1 out of every 3 Americans reports getting sunburned each year. Sunburn is a clear sign of overexposure to UV rays, a major cause of skin cancer.
More than 400,000 cases of skin cancer, about 6,000 of which are melanomas, are estimated to be related to indoor tanning in the U.S. each year.
Tanned skin is damaged skin, yet nearly 1 out of every 3 young white women engages in indoor tanning each year.
Choose sun protection strategies that work:
- Wear a hat, sunglasses, and other protective clothing, seek shade, especially during midday hours.
- Use broad spectrum sunscreen with SPF 15+ to protect any exposed skin. Remember that sunscreen is most effective when used in combination with other methods, and when reapplied as directed.

Damage To The Muscles Nerves And Bones
If melanoma goes untreated long enough, there are instances where the it may grow deeply enough to affect muscle, says Lucas. As far as it goes down, we have to remove it if it involves the muscle, it has to go. Sometimes skin cancers can go so deep they can even go into bone.
The temporal branch allows you to raise your eyebrows, says Lucas. The surgeon may have to take some of those nerves to remove the cancer. In that situation, the patient may not be able to raise their eyebrow after the surgery, and that can be a permanent change, she says.

Types Of Skin Malignancies:
- Melanoma the least common form of skin cancer, but responsible for more deaths per year than squamous cell and basal cell skin cancers combined. Melanoma is also more likely to spread and may be harder to control.
- Nonmelanoma malignancies:
- Squamous cell cancer the second-most common skin cancer. It’s more aggressive and may require extensive surgery, depending on location and nerve involvement.
- Basal cell cancer the most common form of skin cancer. It is rarely fatal but can be locally aggressive.
These skin malignancies are typically caused by ultraviolet radiation from exposure to the sun and tanning beds.

Screening For Skin Cancer
Again, the best way to screen for skin cancer is knowing your own skin. If you are familiar with the freckles, moles, and other blemishes on your body, you are more likely to notice quickly if something seems unusual.
To help spot potentially dangerous abnormalities, doctors recommend doing regular self-exams of your skin at home. Ideally, these self-exams should happen once a month, and should involve an examination of all parts of your body. Use a hand-held mirror and ask friends or family for help so as to check your back, scalp, and other hard-to-see areas of skin. If you or someone else notices a change on your skin, set up a doctors appointment to get a professional opinion.
How Is Skin Cancer Of The Head And Neck Diagnosed
Diagnosis is made by clinical exam and a biopsy. Basal cell and squamous cell cancers are staged by size and extent of growth. Basal cell cancers rarely metastasize to lymph nodes, but they can grow quite large and invade local structures. Squamous cell cancers have a much higher incidence of lymph node involvement in the neck and parotid gland and can spread along nerves.
Melanoma is staged, based not on size but on how deeply it invades the skin layers. Therefore, a superficial or shave biopsy will not provide accurate staging information used to guide treatment. Melanomas can have a very unpredictable course and may spread to distant organs. Melanomas with intermediate thickness often require sentinel node biopsy, a surgical procedure performed by a head and neck surgeon, to determine if microscopic spreading to lymph nodes has occurred.

Skin Cancer Was Discovered As Long Ago As The Early 1800s
It was discovered by the inventor of the stethoscope, a French physician called Rene Theophile Hyacinthe Laënnec.3
There are several types of skin cancer
Melanoma is the most deadly, killing around 55,000 people worldwide, each year4 thats one person every 10 minutes.
Basal cell carcinoma is one of the most common cancers, and while it rarely metastasizes, it can be quite disruptive and disfiguring.
Incidences of skin cancer are increasing worldwide, the number of people dying each year from skin cancer has more than doubled since 1990.5
At least 1 in 5 people diagnosed with metastatic melanoma do not survive longer than five years.6
How To Identify Skin Cancer
Identifying skin cancer is usually easy because it usually occurs on areas of the skin exposed to the sun, such as the scalp, the backs of the hands, the ears, or the lips. It can, however, occur on other parts of the body, such as the palm, under the toes and fingernails, and in the genital area.
Warning signs of skin cancer can include:
- A red, firm nodule
- itching
- Bleeding
Some may have a suspicious spot without any other symptoms. They can be perfectly healthy apart from the annoying spots. If the spots appear unusual, it is best to see a dermatologist for early detection of skin cancer.

Risk Of Further Melanomas
Most people treated for early melanoma do not have further trouble with the disease. However, when there is a chance that the melanoma may have spread to other parts of your body, you will need regular check-ups.
Your doctor will decide how often you will need check-ups everyone is different. They will become less frequent if you have no further problems.
After treatment for melanoma it is important to limit exposure to the sun’s UV radiation. A combination of sun protection measures should be used during sun protection times .
As biological family members usually share similar traits, your family members may also have an increased risk of developing melanoma and other skin cancers. They can reduce their risk by spending less time in the sun and using a combination of sun protection measures during sun protection times.
It is important to monitor your skin regularly and if you notice any changes in your skin, or enlarged lymph glands near to where you had the cancer, see your specialist as soon as possible.
When Should I Call My Doctor
You should have a skin examination by a doctor if you have any of the following:
- A personal history of skin cancer or atypical moles .
- A family history of skin cancer.
- A history of intense sun exposure as a young person and painful or blistering sunburns.
- New or numerous large moles.
- A mole that changes in size, color or shape.
- Any mole that itches, bleeds or is tender.
A note from Cleveland Clinic
Receiving a diagnosis of melanoma can be scary. Watch your skin and moles for any changes and seeing your doctor regularly for skin examinations, especially if youre fair-skinned, will give you the best chances for catching melanoma early when its most treatable.
