Redness or new swelling beyond the border of a mole. Color that spreads from the border of a spot into surrounding skin. Itching, pain, or tenderness in an area that doesn't go away or goes away then comes back. Changes in the surface of a mole: oozing, scaliness, bleeding, or the appearance of a lump or bump.
Early stage skin cancer may resemble a small spot or discolored blemish significantly smaller than the size of a fingernail. It may be reddish or brown, though sometimes white with flaking skin cells surrounded by a small blotch of darker skin.
Any unusual sore, lump, blemish, marking, or change in the way an area of the skin looks or feels may be a sign of skin cancer or a warning that it might occur. The area might become red, swollen, scaly, crusty or begin oozing or bleeding. It may feel itchy, tender, or painful.
Stage 1A means the: melanoma is less than 1 mm thick. outer layer of skin (epidermis) covering the tumour may or may not look broken under the microscope (ulcerated or not ulcerated)
Border that is irregular: The edges are often ragged, notched, or blurred in outline. The pigment may spread into the surrounding skin. Color that is uneven: Shades of black, brown, and tan may be present. Areas of white, gray, red, pink, or blue may also be seen.
The first sign of a melanoma is often a new mole or a change in the appearance of an existing mole.
The most common type of melanoma usually appears as a flat or barely raised lesion with irregular edges and different colours. Fifty per cent of these melanomas occur in preexisting moles.
Does skin cancer itch? While skin cancers are often asymptomatic, meaning they don't show symptoms, they can be itchy. For instance, basal cell skin cancer can appear as a raised reddish patch that itches, and melanoma can take the form of itchy dark spots or moles .
Bumps that are cancerous are typically large, hard, painless to the touch and appear spontaneously. The mass will grow in size steadily over the weeks and months. Cancerous lumps that can be felt from the outside of your body can appear in the breast, testicle, or neck, but also in the arms and legs.
Amelanotic melanoma is an aggressive type of skin cancer that doesn't produce the pigment melanin, which gives most melanomas their dark appearance. As a result, they don't look like other melanomas. Instead, they may appear skin-colored, pink or even reddish, with gray or brownish edges.
According to the American Cancer Society, most skin cancers don't cause painful symptoms until they grow quite large. It's important to see a doctor if you have a suspicious mark on your skin even if it doesn't hurt. Sometimes skin cancer does cause pain.
Crusting or scabbing can be a melanoma indicator. A scabbing mole may be especially worrisome if it also bleeds or is painful. So can other changes, including size, shape, color, or itching. Melanomas can scab because the cancer cells create changes in the structure and function of otherwise healthy cells.
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.
Squamous cell carcinoma initially appears as a skin-colored or light red nodule, usually with a rough surface. They often resemble warts and sometimes resemble open bruises with raised, crusty edges. The lesions tend to develop slowly and can grow into a large tumor, sometimes with central ulceration.
Squamous Cell Carcinoma Warning Signs
Though not as common as basal cell (about one million new cases a year), squamous cell is more serious because it is likely to spread (metastasize). Treated early, the cure rate is over 90%, but metastases occur in 1%–5% of cases. After it has metastasized, it's very difficult to treat.
What does SCC look like? SCCs can appear as scaly red patches, open sores, rough, thickened or wart-like skin, or raised growths with a central depression. At times, SCCs may crust over, itch or bleed. The lesions most commonly arise in sun-exposed areas of the body.
Symptoms of stage 4 squamous cell carcinoma usually begin with some kind of skin lesion or growth. Often, the tumors of squamous cell carcinoma look like a scaly red patch of skin that won't heal. These tumors are often crusty and raised, and they may cause sores or ulcers that last for several weeks.
At first, a basal cell carcinoma comes up like a small "pearly" bump that looks like a flesh-colored mole or a pimple that doesn't go away. Sometimes these growths can look dark. Or you may also see shiny pink or red patches that are slightly scaly. Another symptom to watch out for is a waxy, hard skin growth.
Nodular BCC looks like a dome-shaped bump. It may be pearly or shiny. Typical colors are pink, red, brown, or black. You may see tiny blood vessels in the lesion.
