In general terms, cancer occurs when the cell cycle is no longer regulated due to DNA damage. The number of potential underlying causes of this DNA damage is great, so there are many different risk factors for cancer. Any cells that become cancerous divide more quickly than normal cells. They may form a mass of abnormal cells called a

While pre-metastatic tumors can certainly be dangerous or painful, treatment can be fairly localized, e.g. surgical excision and directed radiation therapy. Once the tumor metastasizes it must be treated systemically due to the potential for secondary tumors literally anywhere in the body. This presents a problem because the tumor cells are derived from the body’s cells and are mostly indistinguishable.

These traits explain how cancer cells proliferate uncontrollably and evade normal biological processes that would typically suppress their growth.

It notes the potential of angiogenesis inhibitors, like angiostatin and endostatin, in treating tumors, as well as emerging therapies such as Vitaxin and Bevacizumab that seek to target angiogenesis. However, it also advises caution, as increased blood supply might be necessary for certain cancers.

This occurs because the basal stem cells in the stratum basale are triggered to divide more often to increase the thickness of the skin at the point of abrasion to protect the rest of the body from further damage.

Originating from mutated cells, cancers involve genetic diversity and are driven by cancer stem cells. Common causes include DNA-damaging agents and viruses, although cancer itself is not contagious. Notably, certain viral infections can elevate cancer risk.
