Skin cancer

Initial skin cancer symptoms

Skin cancers are mainly divided into non-melanoma and melanoma skin cancers, electronic dermatoscope and symptoms vary.

There are two main types of non-melanoma, basal cell carcinoma and squamous cell carcinoma.

Basal cell carcinoma usually starts as a painless, protruding mass that grows slowly and gradually eats away at the surrounding skin, 365nm UV Lamp but rarely moves to other organs and is therefore unlikely to be fatal.

Unlike basal cell carcinomas, squamous cell carcinomas tend to be more aggressive, with a small mass early on that grows larger over time and begins to ulcerate.

Melanoma skin cancer is a relatively rare form of skin cancer because melanocytes become cancerous. In the initial stages, patients often have dark spots on the skin, which gradually grow larger and irregularly shaped, and quickly move to other areas, so they should be treated as soon as possible after diagnosis.

Types and symptoms of skin cancer

The three most common types of skin cancer are basal cell carcinoma (70-85%), squamous cell carcinoma (15-20%), and melanoma (5%). Soft tissue sarcomas in the dermis and subcutaneous tissues are rare in China.

Basal cell carcinoma

Basal cell carcinoma has several characteristics: First, it grows slowly because it grows slowly compared to other malignancies, which is why it is often overlooked; Second, the probability of metastasis is very low, and the basal cell carcinoma rarely invades other organs, and only erodes the nearby skin at most. Third, the mortality rate is very low because basal cell carcinoma is almost non-metastatic, so the mortality rate is very low. Early detection is usually curable.

The basal cell carcinoma of white people is usually flesh-colored or pink, which is different from the basal cell carcinoma of white people, while the basal cell carcinoma of Asian people is often black and looks like a mole, so it is often overlooked. If you have a mole on your body, it will burst and bleed. If you look closely at the surface with some blood vessels, you should be careful of having a basal cell carcinoma. A dermatologist recommends or recommends a detailed examination.

Squamous cell carcinoma

Squamous cell carcinoma is the result of squamous cell damage. Unlike basal cell carcinomas, squamous cell carcinomas are more likely to change. If it is found too late to invade blood vessels and lymphatic vessels, and then metastasize to other organs, surgical resection at this time may also have recurrence, and the prognosis is poor.

Squamous cell carcinomas, which mostly occur on skin that is often sunburned or burned, grow faster and are more aggressive and diffuse than basal cell carcinomas. In addition, squamous cell carcinoma has different appearance shapes and is usually diagnosed after taking a biopsy sample for examination.

melanoma

Melanoma is one of the rarer forms of skin cancer. Melanoma usually occurs on the thighs in women and on the back in men. Although this type of skin cancer is relatively rare, it is a very simple and easily metastatic skin cancer, and only when detected in the early stage can there be a cure.

Melanoma is the most dangerous type of skin cancer and one of the leading causes of death for people with skin cancer. However, melanomas are more common in Caucasians, and some are caused by mole transformation. If there are suddenly enlarged ink moles, irregular edges and color changes, accompanied by itching, it is important to consult a dermatologist as soon as possible.
