To answer "Why is keratin production increased in cancer cells?" We need to understand what cancer is. I strongly believe that as opposed to the conception that cancer is a malfunction; cancer is a highly intentional set of events and not a mistake. The "purpose" of cancer in the body is to protect the body from a quick destruction. Cancer develops in areas of the body where a process of cell destruction is taking place due to chronic inflammation, toxins, prolong lack of adequate blood flow, etc. as a result, normal cells are unable to live in that location and they begin to die. As normal cell start to disintegrate, the living conditions will get worse and that can lead to total organ destruction and quick death. The solution the body has "found" is the cancer cell. Cancer cells can live in such conditions. They can flourish in acidic, low oxygen conditions. They are continuously multiplying, so they can survive. They intensively produce new blood vessels to the highly toxic low oxygen area so normal conditions may be regained. When the stress that led to the deterioration is cleared then the conditions do not favor cancer any more and it may be dest royed by the body's immune system. If the stress is not cleared then the body has gained several extra years. Now to answer "Why is keratin production increased in cancer cells?" Keratin offers better protection from external stimuli such as strong toxins. Some times the conditions are too harsh for "ordinary" cancer and it needs the extra protection of the keratin.
Keratin
It is called Keratinocyte, which is in the outermost layer of the epidermis.
S. corneum - all or mostly dead cells cells are dead, flat, "bags" of keratin
Keratin is found in hair and nails. And rhinocerous horns.
Melanin is formed by the melanocytes which are in the stratum basale of the epidermis. Keratin is formed by the epithelial cells of the skin in the epidermis.
pre cancer cells are cells with an abnormal appearance suggestive of an increased cancer risk. These cells are not cancerous by themselves alone.
Cancer cells begin when something goes wrong with the growth of cells which causes cell production to rapidly and uncontrollably
My best guess is keratin, but I am not sure if that is the cells or the cells are inside the keratin.
Keratin
produced by cells in the breast and increased levels can be associated with breast cancer.
They are made out of keratin. Keratin is made out of dead cells packed real tight.
Research also showed that T-cell and macrophage activity and interferon production were increased in patients using the Chinese herbs ganoderma , lentinus, and polyporus, helping the body fight cancer cells
they can fight the cancer cells
it would stop the production of cancer cells
It is called Keratinocyte, which is in the outermost layer of the epidermis.
S. corneum - all or mostly dead cells cells are dead, flat, "bags" of keratin
Keratinocytes or squamous cells produce keratin and Melanocytes produce melanin, pigment.
