Common skin changes or abnormalities
- Moles: often benign, but changes in color, size, or shape may indicate melanoma, a type of skin cancer. Melanoma is a serious disease that requires immediate medical attention. We recommend that you visit a dermatologist if you notice changes in your moles.
- Lesions: can be caused by infections, allergies or even cancer. Basal cell carcinoma and squamous cell carcinoma are two types of skin cancer that can manifest as lesions. If you notice new or unusual lesions, we recommend that you visit a dermatologist. In some cases, a biopsy may be needed to determine if the lesion is cancerous.
- Rashes: can signal underlying medical problems, such as lupus or psoriasis. If you have an unexplained rash that doesn't go away with over-the-counter medications, we recommend seeing a dermatologist or rheumatologist. They can help you determine the underlying cause of your rash and provide appropriate treatment.
More severe and life-threatening skin conditions
- Melanoma: a type of skin cancer that can be deadly if left untreated. If you notice new moles, changes in the size or shape of an existing mole, or any unusual skin growths, we recommend that you visit a dermatologist immediately. Early detection and treatment can significantly increase the chances of survival.
- Kaposi's sarcoma: a type of cancer that affects people with weakened immune systems, such as those with HIV or AIDS. May cause red or purple lesions on the skin, mouth, and other areas. We recommend visiting an oncologist if you have HIV or AIDS and notice unusual skin growths or lesions. Treatment for Kaposi's sarcoma may include chemotherapy, radiation, or surgery.
- Merkel's cell carcinoma: a rare but aggressive type of skin cancer that often appears as a painless lump on the skin. It can spread quickly and be difficult to treat if not caught in time. We recommend visiting a dermatologist or oncologist if you notice any unusual lumps or formations on your skin. Treatment for Merkel's cell carcinoma may include surgery, radiation, or chemotherapy.
