malignant melanoma
The cells that produce color (melanin) in the skin can become cancerous and this cancer is called melanoma.
Yes. Nickel is a Carcinogen, which means it is capable of causing cancer.
Melanocytes are found in the epidermis, mixed amongst the rest of your skin cells, known as keratinocytes. When a melanocyte gets exposed to UV rays (ie the sun) it secretes melanin, and puts it into little packages (vesicles) called melanosomes. It delivers the melanosomes to the surrounding keratinocytes, which break them open with lysosomes to release the melanin into their cytoplasm. The melanin then goes to surround the nucleus of the cells, and protect its DNA from any more UV light. If you look at cells with lots of melanin vs. cells with little melanin under a microscope, you will notice that the cells with lots of melanin have very dark nuclei.
Radiation exposure is very dangerous because in your skin, contain cells that contain melanin which is a pigment. Melanin cells determine the color of your skin and when a melanin cells is ready to reproduce to make more the DNA is copied and if your in radiation at the time, the radiation can mutate the DNA and over time, the mutated cell will replicate over and over again which can be considered as a type of skin cancer. So I'd suggest staying out of the suns radiations or use sunblock and re-apply every so often(:
there isn't any that i know of because it can even start in the blood forming tissue then enter the blood slowly and spreading to other parts of the body.

If one has less melanin he or she will be more prone to sun burn, which leads to skin cancer. Also, if a lot of melanin groups up in one area (mole), it can become cancerous and lead to skin cancer.
it is capable of killing you :)
It absorbs UV rays so they do not damage DNA and cause skin cancer.

Yes. The Amish are very capable of getting cancer.
Yes. Skin contains a chemical called melanin, which absorbs ultraviolet light, thereby protecting against skin cancer. Races from sunnier parts of the world have stronger types of melanin than those from less sunny places. This gives them better protection. It also makes their skin darker, because the melanin absorbs visible light as well.

Stomach cancer (also known as gastric cancer) is a disease in which the cells forming the inner lining of the stomach become abnormal and start to divide uncontrollably, forming a mass called a tumor.

A malignant tumor (cancer) that originates in glandular tissue is called an adenocarcinoma.
