A New Approach To Fight Cancer

Out of control: biologists still cannot explain why cancerous cells will proliferate and spread to other organs if unchecked

The Final Frontier In The War On Cancer -- The Telegraph

Frustrated by glacial progress, the US has turned to physicists to fight the disease, reveals Paul Davies.

When President Nixon declared war on cancer 40 years ago, he also sanctioned one of the biggest research programmes in history. The budget of America’s National Cancer Institute (NCI) is now $5 billion a year, more than Nasa spends on space exploration. Cancer accounts for a large slice of research funds in most other developed countries, too: Cancer Research UK, for example, has a budget of £500 million a year.

Lung Cancer Rates Double In Women Over 60 Since 1970s -- The Telegraph

Lung cancer rates for retired women have more than doubled since the mid-1970s because of an increase in the number of female smokers, new figures have shown.

Rates for British women aged 60 and over rose from 88 per 100,000 in 1975 to 190 per 100,000 in the latest figures from 2008.

Almost 5,700 women over 60 were diagnosed with lung cancer in 1975. This jumped to more than 15,100 in 2008.

The rise, revealed by Cancer Research UK, can almost all be attributed to increase in smoking among women in the latter half of the last century.

Men on the other hand have seen a dramatic decrease in rates as millions have stopped smoking over the same period.

My Comment: More proof that smoking increases the chances of getting cancer.

Identifying Skin Cancers With Laser Light

New Handheld Melanoma Scanner Instantly Identifies Skin Cancers With Laser Light -- Popular Science

Yeah, you’ve been thinking about getting that thing checked out, but it’s just a mole right? Such is the problem with melanoma; it’s tough to know which spots on the skin are benign and which could be the hallmark of early-stage skin cancer. Most dermatologists still decide which moles require a biopsy by good old fashioned eye-balling, but a new device developed by researchers at British Colombia Cancer Agency (BCCA) could remove that guesswork, using a handheld laser to quickly identify problem spots that require closer examination.

New Chip Captures Hard-to-Find Tumor Cells

From Technology Review:

The devices may one day help patients skip invasive and painful biopsies.

Technologies that analyze cancer cells that circulate through a patient's bloodstream could provide a less invasive way of monitoring cancer and selecting the best treatments. So Mehmet Toner and collaborators at Massachusetts General Hospital have developed a microfluidics chip that effectively captures these rare cells, which make up just one in a billion cells in blood, in high enough numbers to analyze them for molecular markers. The device also isolated clusters of tumor cells for the first time, which may help shed light on cancer's ability to spread, or metastasize, from its initial birthplace.
