Some cancers may just regress

 

Cancer experts had known about the fact that certain types of cancers in the rarest of cases could subside on their own. However, that belief had never been verified. Now, researchers who tracked breast cancer rates in Norwegian women proposed the controversial notion on Monday that some tumors found with mammograms might otherwise disappear on their own if left undetected.

 

Melanomas, kidney cancers and neuroblastoma (a rare childhood tumour) have been known to simply vanish away without treatment.

 

The good news...

Per-Henrik Zahl of the Norwegian Institute of Public Health in Oslo and Norwegian and US colleagues examined invasive breast cancer rates among nearly 120,000 women age 50 to 64 who had a mammogram — an X-ray of the breast used to find evidence of cancer — every two years over a six-year period. They compared the number of breast cancers detected with another group of about 110,000 Norwegian women of the same age and similar backgrounds who were screened just once at the end of the six-year period.

The researchers said they expected to find no differences in breast cancer rates but instead found 22% more invasive breast tumors in the group who had mammograms every two years. This raises the possibility that some cancers somehow disappear naturally, although there is no biological reason to explain how this might be, according to Zahl, whose findings were published in the Archives of Internal Medicine.
