The most obvious sign of skin cancer

Symptoms of skin cancer can include a variety of abnormal changes on the skin. Here are some common signs:

1. Recurrent skin ulcers: If small patches appear on the skin surface, followed by ulcers, and these ulcers are not easy to heal on their own, or even reappear and spread, this may be a sign of skin cancer.

2. Local skin sclerosis: Hard plaque-like papules appear at the base of the skin, which are wart-like protrusions and may deteriorate into ulcers.

3. Skin bulges: Under sunlight, pearly or scaly raised proliferative tissue may appear at the site of skin cancer, and sometimes dilated small blood vessels may be seen in the tumor.

4. Changes in moles or spots: Newly appeared moles or spots, or changes in color or increase in size of existing moles or spots, may also be early signs of skin cancer.

5. Ulcers or rashes that keep appearing: Long-standing ulcers or rashes, especially when they are difficult to heal or continue to grow, should raise the possibility of skin cancer.

6. Tingling or itching: If a certain part of the skin continues to feel tingling or itching and there is no clear external stimulus, this may also be an early sign of skin cancer.

7. Cell proliferation: Rough and thick lumpy or scaly lesions formed on the skin surface, usually accompanied by cell proliferation.

Skin lesions that do not heal for a long time: If unexplained swellings, ulcers, black spots, etc. appear on the body, and these skin lesions do not heal for a long time, you should seek medical attention in time.

8. Gradually enlarging skin nodules: If a rash persists and continues to grow larger and bulges, it may be caused by the continued proliferation of skin cancer lesions.

9. Other accompanying symptoms: such as local pain, secretion of pus, easy bleeding, etc., may also be signs of skin cancer.

The above signs only indicate the risk of skin cancer and cannot be used as a basis for diagnosis. If any of the above symptoms occur, you should seek medical attention for professional examination in time for early detection and early treatment. At the same time, maintaining a good diet and lifestyle, avoiding sun exposure, and regular physical examinations are also effective ways to prevent skin cancer.
