Prior research has linked obesity with worse breast cancer outcomes, but the mechanisms involved were unclear, note Dr. Abenaa M. Brewster and colleagues from the University of Texas M. D. Anderson Cancer Center in Houston.
Prostate cancer diagnosis tends to be delayed and surgical treatment more difficult in obese men than in lean men, according to two studies published Friday.
The primary reason for the later diagnosis, and consequently poorer prognosis, seems to be that the PSA test used to screen for prostate cancer is "biased" against obese men, according to researchers.
An injection of a high dose of vitamin C may be able to hold back the advance of cancers, US scientists claim.
The vitamin may start a destructive chain reaction within the cancer cell, they add.

Screening women with both ultrasounds and mammograms allows doctors to find more breast cancers than if they rely on mammograms alone, a new study shows. However, the combination also leads to many more unnecessary biopsies, and experts don't recommend it to most patients.
By activating a cancer suppressor gene, a small molecule called nutlin-3a can block cancer cell division, according to researchers at the National Cancer Institute (NCI), part of the National Institutes of Health. This activation of the p53 gene leads to cellular senescence, a process by which cells lose their ability to grow and divide.
The numbers are staggering. But, even more shocking is a new study by an Australian neurosurgeon. He says ten years of cell phone use can double your risk of a brain tumor.
Bowel cancer is frequently not detected until the disease is well-established, sharply reducing the chances of successful treatment.
