Basal and Squamous Cell Skin Cancer
Skin cancers often don't cause bothersome symptoms until they have grown quite large. Then they may itch, bleed, or even hurt. But typically they can be seen or felt long before they reach this point.
Basal cell cancers usually develop on areas exposed to the sun, especially the face, head, and neck, but they can occur anywhere on the body.
These cancers can appear as:
Basal cell cancers are often fragile and might bleed after shaving or after a minor injury. Sometimes people go to the doctor because they have a sore or a cut from shaving that just won’t heal, which turns out to be a basal cell cancer. A simple rule of thumb is that most shaving cuts heal within a week or so.
Squamous cell cancers tend to occur on sun-exposed areas of the body such as the face, ear, neck, lip, and back of the hands. Less often, they form in the skin of the genital area. They can also develop in scars or skin sores elsewhere.
These cancers can appear as:
Both basal and squamous cell skin cancers can also develop as a flat area showing only slight changes from normal skin. To see some examples of basal and squamous cell cancers, visit our Skin Cancer Image Gallery.
These and other types of skin cancers can also look different from the descriptions above. This is why it’s important to have a doctor check any new or changing skin growths, sores that don’t heal, or other areas that concern you.
