What the best cancer specialist has to say about skin cancer

By Noida India

Skin cancer is a malignancy marked by the abnormal growth and multiplication of skin cells that result from the exposure to the harmful radiations of the sun. However, sun exposure is not the only cause of skin cancer as it may also affect areas of the skin that are not usually exposed to the sunlight, which includes your palms, hands, toenails etc. It is also pertinent to note that the risks of skin cancer are significantly high in poorly pigmented individuals.

Top Cancer specialists usually classify skin cancer into 3 major categories i.e. basal cell carcinoma, squamous cell carcinoma and melanoma.

Recognizing the symptoms:

Best oncologists in Noida suggest that the symptoms of skin cancer vary depending upon the type of cancer and where it originates.

  • Basal cell carcinoma develops in the basal cells that lie just beneath the squamous cells and are responsible for generating new skin cells. Basal cell carcinoma affects areas that are exposed to sunlight, i.e. your face and neck. Common symptoms include a waxy bump on the skin, brownish scars or lesions, recurrent bleeding or scabbing.

  • Squamous cell carcinoma, too, affects in those areas of the body that are exposed to the sun i.e. your face, neck and ears. However, the problem is more likely to affect people with a darker skin tone. Squamous cells lie just beneath the topmost layer of the skin i.e. the epidermis. Major symptoms include red nodules that are quite firm and scaly lesions.

  • Melanoma can affect any part of your body whether it is exposed to the sun or not. Melanocytes are the cells responsible for producing melanin i.e. the colouring pigment of the skin. Increased production of melanin allows deeper penetration of the harmful radiations of the sun into the skin, thereby increasing the risks of cancer. In some cases, even an existing mole can become malignant. In the case of males, it mostly affects the face and trunk whereas, in the case of females, it is likely to develop on the lower parts of the legs. Symptoms of melanoma include large brown spots on the skin, change in the shape, size or colour of a mole, small, painful and dark lesions with irregular lining.

What causes skin cancer?

Skin cancer is triggered by abnormal or unhealthy mutations in the DNA of your skin, which cause the skin cells to multiply uncontrollably. Skin cancer though affects people of all age groups, is more likely to affect elderlies. Also, if you’ve had skin cancer once in your life, you are at a slightly higher risk of developing it again. Skin cancer usually begins in the top layer of the epidermis and is a result of:

  • Exposure to ultraviolet light, either directly coming from the sun or used in tanning beds. You will be surprised to know that people with fair skin and especially those who are blond, are particularly vulnerable to it.

  • Immune system suppression that might be a result of an underlying disease, medication or high-intensity therapies, like chemotherapy or radiation therapy.

  • Prolonged exposure to ionizing radiation or chemicals like arsenic.

  • Sexually transmitted wart viral infections.
