Cancer

This section will maintain key information and medical advancements relating to cancer – how to prevent it and what treatments are available.

Not every new story – just major breakthroughs and studies on ways to prevent. Particularly will be focusing on research results in humans – lots of promising treatments unfortunately never make it from the lab, through human trials, and onto the market.

Wide range of cancers now linked to being overweight – NHS Choices – 1-Mar-2017
Strong evidence people who are overweight have an increased risk of developing 11 different cancers.
Most of them either digestive (such as bowel cancer) or hormonal (such as breast cancer).

Blood test could catch pancreatic cancer before it’s too late – New Scientist – 8-Feb-2017
Because the pancreas is deep inside the body and is difficult to image or biopsy, spotting the cancer is hard.
Only 5 per cent of people diagnosed with pancreatic cancer are still alive five years later.

In a pilot study in 59 patients, it picked up early-stage pancreatic cancer in more than 90 per cent of cases.

Crowd funding success for OncoSENS Control ALT Delete Cancer – SENS Research Foundation – 18-Sep-2016
$72,000 raised for high-throughput screening of a library of diverse drugs to find treatments for ‘ALT’ cancers.
ALT cancers rely on Alternative Lengthening of Telomeres.
Telomere shortening acts as a biological mechanism for limiting cellular life span.
Most cancer cells bypass this failsafe by synthesizing new telomeres using the enzyme telomerase.
There are currently no ALT-targeted anti-cancer therapeutics.

Also used women’s own estimates of their weight at ages 18, 35 and 50.

Universal cancer vaccine breakthrough – Independent – 2-Jun-2016
Nanoparticulate RNA immunotherapy puts pieces of cancer’s genetic RNA into tiny nanoparticles of fat and injects into the bloodstream.
Patient’s immune systems respond by producing T-cells designed to attack cancer.
Successful safety trial in three patients in the advanced stage of disease – also saw positive results.
Vaccine also effective in fighting aggressively growing tumours in mice.
Such vaccines are fast and inexpensive to produce and could target virtually any type of cancer.

What will President Obama’s cancer ‘moonshot’ achieve? – BBC News – 9-Apr-2016

Cancer is the most complex disease that we know of.
Money will fund research into:
– new treatments (e.g. combining treatments and immunotherapy)
