cancer pen

A patient told me about the “cancer pen” yesterday. I promptly pictured  Star Trek’s Bones holding his device over patients, but no, this has to touch tissue…aka a piece of you…and do a chemical evaluation. It is to be used during surgery.

This is neat new technology… but. I can hear my sister saying, “Uh, so what about PREVENTION?”

This is technology to remove cancer after it’s already grown. And presumably metastasized. So this is stage II, stage III, stage IV cancer.

Cancer deaths are the second biggest cause of death in the US. Around 23% of yearly deaths and that does not count the people who survive cancer. At present we do not have many screening tests for cancer: pap smears continue to evolve, and now the recommendation is an HPV test or pap smear every five years AND we have a vaccine for the high risk HPV.
We can screen for colon cancer.
Mammograms for breast cancer.
The screen for prostate cancer sucks.
We can do skin checks.
The screen for lung cancer is now a low dose CT in a certain population that is high risk, that is, smokers. The recommendations have not addressed smoking marijuana.
Recommendations in the US are here: https://www.uspreventiveservicestaskforce.org/.

There are lots of cancers that we don’t have screens for…. yet.

Proteomics is on the horizon. Genomics is looking at the genes, but it turns out that lots of cancers and infections and other illnesses have particular protein patterns. There is TONS of research in this area. Someday we may have protein tests: put a drop of blood or urine on it and say, “Hmmm. Looks like you have a positive test, probable lung cancer.”

That in turn creates problems. Initially we may be able to diagnose a cancer but not FIND it. Also not know how to treat it. The first big study trying to set up lung cancer screening had over 600 worrisome CT scans out of 1000. How many lung cancers did they find? Nine. And half of the nine had symptoms and could be found on chest xray by the time they did repeat CTs. Think of the anxiety of the 600 people who might have cancer and “We will repeat the CT scan in four months. Don’t worry too much.” Also there were complications from biopsying the lungs, like bleeding and pneumonia….

The best bet to avoid cancer is still living in a healthy way: don’t smoke anything, avoid addictive substances, eat good food, exercise, have friends and loved ones, work for yourself and your community, do some things you love…..

 

I took the photograph of my sister in 2011. She died of breast cancer in 2012. Her blog is here: butterfly soup.

For the Daily Prompt: strut. Struts support things: airplane wings, cars, things that move. How do we as a culture support people to live healthy lives?
