ah, my wife has been in histology longer than i have known her. she now runs a huge lab.
biopsy proof is just proof of biopsy. we all have cancer cells in us that come and go as the immune system works on them. the big push on early detection is to find masses before the body can deal with them. they would have healed anyway but the doctors take the credit. the ones that are too sick to withstand the chemo and radiation usually die of those. its always attributed to the cancer. its all the cancers fault.
the thing to do is to ad an anti-cancer program to your self health regimen. iodine, selenium and boron are a huge step in the right direction.
