Understanding The Difference Between Cure And Remission
Cure means that there are no traces of your cancer after treatment and the cancer will never come back.
Remission means that the signs and symptoms of your cancer are reduced. Remission can be partial or complete. In a complete remission, all signs and symptoms of cancer have disappeared.
If you remain in complete remission for 5 years or more, some doctors may say that you are cured. Still, some cancer cells can remain in your body for many years after treatment. These cells may cause the cancer to come back one day. For cancers that return, most do so within the first 5 years after treatment. But, there is a chance that cancer will come back later. For this reason, doctors cannot say for sure that you are cured. The most they can say is that there are no signs of cancer at this time.
Because of the chance that cancer can come back, your doctor will monitor you for many years and do tests to look for signs of cancers return. They will also look for signs of late side effects from the cancer treatments you received.
What Are The Survival Rates For Bcc
Cancer registries do not collect information about basal cell carcinoma because the majority of BCCs are diagnosed and treated easily in a doctors office.
Advanced BCC is so rare that there is very little information about survival rates. One study of 100 cases of metastatic BCC between 1981 and 2011 showed that median overall survival is 4.5 years. How far the cancer spread made a big difference in survival. For regional metastasis, survival was 7.2 years. For distant metastasis, it was 2 years. These estimates are based on a time when chemotherapy or radiation therapy were the only treatment options.9
Survival time with advanced BCC might be improving with newer treatments. In trials for a targeted therapy called Erivedge® , median overall survival was 2.8 years. The 1-year survival rate was 84.4 percent and the 2-year survival rate was 68 percent. Odomzo® , another targeted therapy, has similar survival outcomes. Trials of sonidegib show that 2-year survival is 93 percent for people with locally advanced BCC and 69 percent for people with metastatic BCC.10,11
Looking For Signs Of Skin Cancer
Non melanoma skin cancers tend to develop most often on skin that’s exposed to the sun.
To spot skin cancers early it helps to know how your skin normally looks. That way, you’ll notice any changes more easily.
To look at areas you cant see easily, you could try using a hand held mirror and reflect your skin onto another mirror. Or you could get your partner or a friend to look. This is very important if you’re regularly outside in the sun for work or leisure.
You can take a photo of anything that doesn’t look quite right. If you can it’s a good idea to put a ruler or tape measure next to the abnormal area when you take the photo. This gives you a more accurate idea about its size and can help you tell if it’s changing. You can then show these pictures to your doctor.

Squamous Cell Skin Cancers
Squamous cell skin cancers can vary in how they look. They usually occur on areas of skin exposed to the sun like the scalp or ear.
Thanks to Dr Charlotte Proby for her permission and the photography.
You should see your doctor if you have:
- a spot or sore that doesn’t heal within 4 weeks
- a spot or sore that hurts, is itchy, crusty, scabs over, or bleeds for more than 4 weeks
- areas where the skin has broken down and doesn’t heal within 4 weeks, and you can’t think of a reason for this change
Your doctor can decide whether you need any tests.

Risks Associated With Untreated Melanoma
Melanoma makes up a very small percentage of overall skin cancer cases. However, melanoma is responsible for over half the annual deaths attributed to skin cancer. Dr. Truong says, Melanomas are an aggressive and quickly evolving form of cancer. Its the most likely to grow quickly and metastasize. A treatment plan should be formulated as soon as possible. When caught and treated early, melanoma has a high cure rate, but when treated in later stages, cure rates drop drastically, especially if the cancer has metastasized.
Within six weeks of initial development, melanoma can become life-threatening, therefore, early treatment is extremely important. In order to access treatment in the earliest stages, patients need to know what to look for. Melanoma develops from the melanocytes, cells that create the skins pigment. For this reason, patients will need to carefully note any existing or new moles, freckles, or dark spots on the skin, assessing the area for the ABCDEs: Asymmetry, uneven Border, inconsistent or unusual Color, Diameter greater than the size of a pencil eraser, and any areas that are Evolving or changing.

Sentinel Lymph Node Biopsy
A sentinel lymph node biopsy is a procedure to test for the spread of cancer.
It may be offered to people with stage 1B to 2C melanoma. It’s done at the same time as surgical excision.
You’ll decide with your doctor whether to have a sentinel lymph node biopsy.
If you decide to have the procedure and the results show no spread to nearby lymph nodes, it’s unlikely you’ll have further problems with this melanoma.
If the results confirm melanoma has spread to nearby nodes, your specialist will discuss with you whether further surgery is required.
Additional surgery involves removing the remaining nodes, which is known as a lymph node dissection or completion lymphadenectomy.
What Do Cancer Survival Rates Mean
When learning about cancer survival rates, its important to keep in mind that these statistics are based on a very large and diverse group of people. Because no two people with squamous cell carcinoma are alike, the general survival rate cannot be used to predict a specific patients outcome. Additionally, survival rates are broad benchmarks. While useful as a baseline point of reference for physicians, this information is not detailed enough to reflect the different treatments people have had, nor is it recent enough to include the results of the latest breakthrough treatments now available to patients through clinical trials .

Risks Associated With Untreated Basal Cell Carcinoma
Basal cell carcinoma is the most common form of skin cancer. Its also the slowest growing of the common forms of skin cancer and the least likely to metastasize, meaning it rarely spreads to other parts of the body. However, basal cell carcinoma presents a risk for disfigurement if left untreated. Without proper intervention, basal cell carcinoma can grow and invade local structures. Additionally, these lesions may present a risk for ulceration , bleeding, and infection. The type of treatment available in the early stages is likely to be more effective, less invasive, and more cost-effective. The longer basal cell carcinoma goes untreated, the procedures necessary to remove it become more advanced, invasive, and costly.

Infiltrative Basal Cell Carcinoma

Infiltrative basal cell carcinoma occurs when a tumor makes its way into the dermis via thin strands between collagen fibers. This aggressive type of skin cancer is harder to diagnose and treat because of its location. Typically, infiltrative basal cell carcinoma appears as scar tissue or thickening of the skin and requires a biopsy to properly diagnose.
To remove this type of basal cell carcinoma, a specific form of surgery, called Mohs, is used. During a Mohs surgery, also called Mohs micrographic surgery, thin layers of skin are removed until there is no cancer tissue left.

Superficial basal cell carcinoma, also known as in situ basal-cell carcinoma, tends to occur on the shoulders or the upper part of the torso, but it can also be found on the legs and arms. This type of cancer isnt generally invasive because it has a slow rate of growth and is fairly easy to spot and diagnose. It appears reddish or pinkish in color and may crust over or ooze. Superficial basal cell carcinoma accounts for roughly 15%-26% of all basal cell carcinoma cases.
Screening For Skin Cancer
While early detection and treatment of skin cancer can improve patient outcomes,4 convincing data regarding the benefit of mass screening programs are lacking.5 In addition, the ability to identify potentially malignant lesions varies with physician training.6 Thus, except for very high-risk persons with a history of skin cancer or atypical mole syndrome, for whom periodic screening is universally recommended, there is considerable debate about who should be screened, who should perform the screening and how often screening should be performed .7 Part of the screening process should include an assessment of patient risk .1,812

Metastatic Melanoma Life Expectancy
The 5-year survival rate for a metastatic melanoma is about 15% to 20% 7). The 10-year survival is about 10% to 15% 8). The outlook is better if the spread is only to distant parts of the skin or distant lymph nodes rather than to other organs, and if the blood level of lactate dehydrogenase is normal.
- The survival differences among M categories will be useful for clinical trial stratification however, the overall prognosis of all patients with stage IV melanoma remains poor, even among patients with M1a. For this reason, the Melanoma Staging Committee recommended no stage groupings for stage IV.

- A sore that doesnt heal
- Spread of pigment from the border of a spot into surrounding skin
- Redness or a new swelling beyond the border of the mole
- Change in sensation, such as itchiness, tenderness, or pain
- Change in the surface of a mole scaliness, oozing, bleeding, or the appearance of a lump or bump
Be sure to show your doctor any areas that concern you and ask your doctor to look at areas that may be hard for you to see. Its sometimes hard to tell the difference between melanoma and an ordinary mole, even for doctors, so its important to show your doctor any mole that you are unsure of.

Basal Skin Cancer What Are The Symptoms Causes And Treatments
Basal skin cancer is also known as basal cell carcinoma which refers to a cancerous lesion that slowly grows on skin then spreads. It is a form of cancer that can damage the tissues and cells in the skin causing ugly-looking skin. However, it is a cancer that is least dangerous although it is a very common skin cancer.
Basal Skin Cancer
The cause of this cancer is due to the UV rays of the sun. Too much exposure to sunlight can cause these lesions to develop. Most cases of this condition are common to Caucasians because of the white skin or lighter complexion they have. There is really a risk factor to develop this cancer if you are extremely exposed outdoors. For instance, if the nature of your work requires you to stay under the sun, you have a greater risk of having the cancer in due time.
There are other causes of basal skin cancer but not really common. They are due to the history of the condition in a family and exposure to carcinogenic chemicals. They may not be as common as the severe sun exposure but these can also contribute in some cases.
Furthermore, the lesions may form ulcer which may require skin examination. If there is a suspicious ulcer in the center of a lesion, you better consult a dermatologist as soon as possible. A dermatologist is more preferable but any good general doctor can be also consulted.

Different Types Of Cancer Start In The Skin
Skin cancer may form in basal cells or squamous cells. Basal cell carcinoma and squamous cell carcinoma are the most common types of skin cancer. They are also called nonmelanoma skin cancer. Actinic keratosis is a skin condition that sometimes becomes squamous cell carcinoma.
Melanoma is less common than basal cell carcinoma or squamous cell carcinoma. It is more likely to invade nearby tissues and spread to other parts of the body.
This summary is about basal cell carcinoma, squamous cell carcinoma of the skin, and actinic keratosis. See the following PDQ summaries for information on melanoma and other kinds of cancer that affect the skin:

Many Factors Can Affect Your Prognosis
Some of the factors that affect prognosis include:
- The type of cancer and where it is in your body
- The stage of the cancer, which refers to the size of the cancer and if it has spread to other parts of your body
- The cancers grade, which refers to how abnormal the cancer cells look under a microscope. Grade provides clues about how quickly the cancer is likely to grow and spread.
- Certain traits of the cancer cells
- Your age and how healthy you were before cancer
- How you respond to treatment

How Does Cancer Start
The human body is made up of trillions of cells. As a person grows older, his body gradually widens. And at the same time, the cells of his body grow and divide as needed. But when something abnormal or old in the cells, the cells usually die.
Cancer starts or occurs when this process of cell death in our body does not work. For this reason, if the old or abnormal cells do not die properly. When new cells are formed, then these old cells come to the new coach and accumulate, which makes it very difficult for your body to function properly.

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.
