Skin Cancer Questions

What causes skin cancer? What is the difference between different cancers and how fast it can spread? Skin cancer is the most common of all cancers and accounts for almost half of all cancers in the United States. If you experience a change in your skin it is important to know what your options for treatment are. Visiting with a verified medical Expert online may be your best starting point. Read below where Experts have provided customized answer to ease concerned individuals minds.

Can an individual get melanoma from a boil?

No, a boil is infectious and caused by bacteria. A melanoma is due to an abnormal and malignant proliferation of the pigment making cells of the skin, the melanocytes.

What is the difference between skin cancer cells and lymphoma cancer cells?

The difference between skin cancer and lymphoma cancer is the cells of origin. For skin cancer, the cancer cells come from either squamous cells (squamous cell carcinoma), basal cells (basal cell carcinoma) or melanin cells (melanoma). For lymphoma, the cancer cells come from cells in lymph nodes.

When should a shave biopsy site on the elbow to remove skin cancer stop oozing and hurting?

The elbow is a tough place to heal because of constant bending and bumping into things. The individual needs to cover the area with Neosporin ointment, and then cover the area with a flexible dressing, that is changed at least twice daily.

Is vulvar cancer classed as a skin cancer?

No, vulvar cancers have their own staging and classification. The most common vulvar cancer is squamous cell cancer which is also a skin cancer, but squamous cell cancers can be anywhere like the cervix, anal canal, tonsil and lungs.

How fast does facial skin cancer spread if it is not removed?

The rate at which it may spread depends on the type of cancer. Some basal cell carcinoma skin cancers can be very slow growing and cause slow bleeding or oozing of blood and non-healing of a spot for years. Some squamous cell carcinoma skin cancers and the most aggressive malignant melanoma can be very fast growing.

How dangerous is squamous cell skin cancer?

Most skin cancers are not very dangerous. The common basal cell carcinoma or squamous cell carcinomas tend to stay on the skin and have a high cure rate with superficial skin radiation therapy or surgery. Malignant melanoma is the most deadly skin cancer which has a high chance of spreading and can be very deadly, but fortunately it is rare.

Could a melanoma spot that was removed from the belly have spread to the internal organs?

There would be a slim chance that this would have spread to other areas of the body.

Could a non-itchy area that is a quarter of an inch around, with three dark reddish/brown marks, be a sign of skin cancer?

It is likely this is not skin cancer, and is just a fungal infection. It could possibly be actinic keratosis or just keratosis. A dermatologist should be consulted to determine what these marks are.

Is perianal Paget’s disease a type of skin cancer and what is the treatment?

Yes, perianal Paget’s disease is what is called extra mammary Paget’s disease which is a low grade skin adenocarcinoma cancer. Radiation therapy treatment is typically a successful cure.

Can skin cancer, or other cancers, develop from having a cat scan?

Yes, radiation-induced cancers may develop decades after exposure, and include melanoma, leukemia, lung cancer, thyroid cancer, breast cancer, bone cancer and skin cancer. Medical imaging, such as a cat scan, uses ionizing radiation, which causes structural damage at the cellular and molecular levels. The proposed mechanism for cellular damage by ionizing radiation involves the production of free radicals. The free radicals interfere with chemical bonds between molecules that regulate key cellular processes. Direct interaction between ionizing radiation and cellular macromolecules leads to DNA mutation or cell death, while indirect interaction causes free radical damage to essential cell enzymes. Tissues are more or less susceptible to radiation injury, based on their rate of cellular proliferation and their degree of cellular differentiation. Thus, blood forming (lymphoproliferative) organs with rapid cell turnover are most sensitive while nervous tissue with little or no cell turnover is least sensitive. 

More than 3.5 million cases of various types of skin cancer are diagnosed each year. Because of these overwhelming numbers, people tend to worry more than necessary.
