The number of people diagnosed with melanoma has risen sharply over the past 3 decades. However, the rates of diagnosis vary by age. For adults in their 30s, the number of people diagnosed with melanoma remained steady for women and dropped slightly for men. The decrease in melanoma in younger people is likely due in part to increased sun-protection behaviors and a reduction in indoor tanning. It is estimated that 7, deaths 4, men and 2, women from melanoma will occur this year.
Many people with melanoma are cured by their initial surgery. The 5-year survival rate tells you what percent of people live at least 5 years after the cancer is found. Percent means how many out of Overall survival at 5 years depends on the thickness of the primary melanoma, whether the lymph nodes are involved, and whether there is spread of melanoma to distant sites. Lymph nodes are small, bean-shaped organs that help fight infection.
However, this number is different for every patient and depends on the number of lymph nodes involved, genetic changes, the amount of tumor in the involved lymph node s , and the features of the primary melanoma such as thickness and whether ulceration is present or absent. However, survival varies depending on a number of factors. Unfortunately, when melanoma cells are carried to the lymph nodes, they can potentially be carried beyond the nodes to distant organs.
The five-year survival rate then drops to around 62 percent because of the high risk that the cancer can spread from the nodes throughout the body. Once a tumor has spread to distant body sites such as organs, it is considered a stage IV melanoma, with an estimated five-year survival rate of only 18 percent in the U. These survival figures are improving every year because of new treatments some therapies are keeping as much as 40 percent of stage IV patients alive for years , but they are no substitute for early detection.
Every melanoma has the potential to become deadly, but the difference between an in situ melanoma and one that has begun to metastasize cannot be overstated. There is a drastic change in the survival rate for the various stages of tumors, highlighting the importance of detecting and treating melanomas before they have a chance to progress.
These skin exams can help you take note of any new or changing lesions that have the potential to be cancerous, and have them biopsied and taken care of before they can escalate.
Each time unprotected skin is exposed to UV radiation from the sun or artificial sources, changes take place in the structure of the cells. Too much UV radiation causes the skin to become permanently damaged, which will worsen with each exposure. Skin cancer can grow when the cells that make up your skin are damaged, causing them to grow abnormally.
Every additional decade of overexposure to UV further increases your risk of skin cancer. Increased use of sun protection will help prevent skin cancer and melanoma at any age. All skin types can be damaged by exposure to UV radiation. People with skin types that are less likely to burn are still at risk of developing skin cancer although this risk is lower than for people with skin types that are more likely to burn.
People with one or more risk factors are at increased risk of melanoma. Risk factors for melanoma are:. The melanin in naturally very dark skin offers some protection against the damaging effects of UV radiation and lowers the risk of skin cancer. However, when skin cancer is detected in people with naturally very dark skin, it is often found at a later, more dangerous stage when the risk of death is much higher.
The first sign of flat melanoma is usually a new spot or an existing mole or freckle that changes in appearance. Some changes might include:.
Melanoma can grow very quickly. It can become life-threatening in as little as 6 weeks and, if untreated, it can spread to other parts of the body. Melanoma can appear on skin not normally exposed to the sun.
Nodular melanoma is a highly dangerous form of melanoma that looks different from common melanomas. Nodular melanomas are raised and are even in colour often red or pink and some are brown or black.
This type of melanoma grows quickly and can be life-threatening if not detected and removed quickly. See your doctor immediately if you notice any of these changes.
It's important to get to know your skin and what is normal for you, so you will notice any changes quickly. Check all of your skin, not just sun-exposed areas. If you notice anything unusual, including any change in shape, colour or size of a spot, or the development of a new spot, visit your doctor immediately.
While melanomas usually occur on parts of the body that have been sunburned, they can sometimes start in parts of the skin or other parts of the body that have never been exposed to the sun. Melanomas on the arms and legs are usually detected earlier and have a better chance of successful treatment than melanomas on the body, neck or head which are usually detected at a later stage. Once a melanoma is diagnosed and treated, you are advised to have regular skin checks, as there is an increased risk of further melanomas developing.
