By comparison, the mutation frequency in the whole genome between generations for humans (parent to child) is about 70 new mutations per generation. [88] [89] In the protein coding regions of the genome, there are only about 0.35 mutations between parent/child generations (less than one mutated protein per generation). [90]
The rate of cancer recurrence is determined by many factors, including age, sex, cancer type, treatment duration, stage of advancement, grade of original tumor, and cancer-specific risk factors. [2] [3] [4] If recurrent cancer has already moved to other body parts or has developed chemo-resistance then it may be more aggressive than original ...
And if the normal stem cells from a tissue divide 100,000 times, the cancer risk in that tissue is approximately 100,000X. This strongly suggests that the main factor in cancer initiation is the fact that "normal" stem cells divide, which implies that cancer originates in normal, healthy stem cells. [37]
Scientist Otto Warburg, whose research activities led to the formulation of the Warburg hypothesis for explaining the root cause of cancer.. The Warburg hypothesis (/ ˈ v ɑːr b ʊər ɡ /), sometimes known as the Warburg theory of cancer, postulates that the driver of carcinogenesis (cancer formation) is insufficient cellular respiration caused by insult (damage) to mitochondria.

People with multiple first-degree relatives who've had breast or ovarian cancer or any cancer before age 50 may also be higher risk for cancer recurrence and therefore undergo a double mastectomy.
One doctor told me that there was nothing they could do to treat me. Another asked if I had considered freezing my eggs (because some types of chemotherapy can lead you into early menopause ).

Colon cancer provides one example of the mechanisms by which diet, the top factor listed in the table, is an external factor in cancer. The Western diet of African Americans in the United States is associated with a yearly colon cancer rate of 65 per 100,000 individuals, while the high fiber/low fat diet of rural Native Africans in South Africa is associated with a yearly colon cancer rate of ...
