You mention PSA so I'm assuming you are referencing prostate cancer.
I'm a prostate cancer survivor, diagnosed from pieces that came out during a
TURP. I was scheduled for prostate removal 15 years ago because of this
then cancelled my surgery date because I didn't wish to deal with the after
effects of removal. Did some healthy eating and added raw garlic to my
diet. Raw garlic kills prostate cancer in the Petri dish. Had my PSA
levels checked every six months for a while, then once a year. The PSA's
were .7 and .75 until about six months ago when it went to 2.3. Ate lots
of raw garlic and two months later my PSA was at 1.3.
Raw garlic kills prostate cancer. It can help your PSAs.
