Skin Cancer

Skin Cancer and Cannabis Oil Treatment

Skin cancer — the irregular growth of skin cells — most frequently develops on skin that is exposed to the sun. However, this common form of cancer can also befall on areas of the skin not ordinarily exposed to sunlight.

There are three main types of skin cancer, namely melanoma, squamous cell carcinoma, and basal cell carcinoma.

You can decrease your risk of skin cancer by avoiding or limiting exposure to ultraviolet radiation. Checking your skin for suspicious changes can help spot skin cancer at its earliest stages. Early detection of skin cancer offers the greatest chance for successful treatment of skin cancer.

Causes

Skin cancer arises when mutations occur in the DNA of skin cells. These mutations cause the cells to grow out of control and result in a mass of cancer cells.

Cells involved in skin cancer

Skin cancer starts in the skin’s top layer — the epidermis. The epidermis is a thin layer that offers a protective cover of skin cells that the body continually sheds. The epidermis comprises three main types of cells:

  • Squamous cells lie just underneath the outer surface and function as the inner lining of the skin.
  • Melanocytes — which produce melanin (the pigment that gives skin its normal colour) are located in the lower part of the epidermis. Melanocytes produce more melanin when a person is in the sun, in order to help protect the deeper layers of your skin.
  • Basal cells produce new skin cells and sit underneath the squamous cells.

Wherever your skin cancer starts, will determine the type and treatment options.

Ultraviolet light and other possible causes

Much of the damage to DNA in skin cells is caused by ultraviolet radiation that is found in sunlight and in the lights that are used in tanning beds. However, sun exposure does not explain skin cancers that develop on skin that is not ordinarily exposed to sunlight. This shows that other factors may contribute to the risk of skin cancer, such as exposure to toxic substances or having a condition that weakens the immune system.

Symptoms

Skin cancer develops mainly on areas of sun-exposed skin, including the face, scalp, lips, ears, neck, arms, chest, and hands, and possibly on the legs of women. However, it can also form on areas that seldom see the light of day — such as the palms, underneath fingernails or toenails, and even on the genital area.

Skin cancer affects people of all skin tones, including people with darker complexions. When melanoma arises in people with dark skin tones, it is more likely to occur in areas that are not normally exposed to the sun, like the palms of the hands and soles of the feet.
