There are many different types of skin cancer, but the most common is basal cell carcinoma, which develops in areas of the body that are constantly exposed to the sun. The basal layer of skin consists of dead cells, while the top two layers of the epidermis are filled with keratin, a protein produced by cells called keratinocytes. In addition, squamous cell skin cancer develops from cells called keratinocytes that are located in the epidermis, a layer just above the basal layer.
A mole may be melanoma, or a benign skin disease, depending on the type and extent of the cancer. Symptoms may include pain, itchiness, swelling, or oozing. Some moles may even become so large that they begin bleeding after a minor injury. Nodular melanomas are a much faster-developing type of melanoma, and they appear as lumps on previously healthy skin.
A person’s risk of developing skin cancer can be greatly reduced by limiting their exposure to the sun, especially between 10 a.m. and 4 p.m. Wearing a hat or other protective clothing is also a good idea. Sunscreens that have a sun protection factor of at least 30 should be applied regularly, at least 20-30 minutes before going outdoors. Protective clothing, such as a hat with a wide brim, should also be worn to protect against UV rays.
When you suspect that you have a skin cancer, you should visit your doctor immediately. In addition to examining the suspicious area, a dermatologist may suggest a biopsy, which is a quick procedure that removes a small piece of skin for testing. Early detection is vital and can save your life. So, be sure to consult a dermatologist as soon as possible! If you see a change in your skin, be sure to take a picture and let your doctor know.
Treatment for skin cancer depends on its stage. If it is small, it can be treated with topical creams, while larger tumors may require surgery or radiotherapy. For more aggressive cases, systemic chemotherapy and immunotherapy may be needed. Sometimes, a combination of these treatments may be recommended. For those who are concerned about the effects of cancer, there is also a supportive care program that can be used to alleviate the symptoms of the disease.
The most common type of skin cancer is basal-cell carcinoma, which affects the most people. It often starts in areas that are not exposed to the sun. It is easy to treat and rarely causes death. It is not always easy to diagnose, and early detection is essential. The Mayo Clinic offers a free health newsletter that features the latest information and research on health care. While the incidence of skin cancer in nonwhites is increasing, the survival rate for black people is significantly lower than for whites.
Another type of skin cancer is melanoma, which can affect people of all skin tones. It typically occurs on the body’s exposed parts, like the face, but can develop on areas that have never been exposed to sunlight. Patients should undergo skin cancer testing if they are experiencing any of these symptoms. You may also be suffering from an unusually high risk of developing skin cancer. If you have any suspicious spots, it’s important to consult a dermatologist as early as possible.
