Hi Susan some of the info I am digesting in small form is when the host cancer cell spreads and lands and starts growing other cancer cells it can change the dna sequence. Such as it is a psa cancer cell 1,2,3,4,5 but when it starts growing its own in the liver it can and might change to 3,1,2,4, 5. It can even add or take away. The oncologist said they had found this happening in Pca. The biopsy Steve is going to have will be tested to see how the cancer has changed from his pca and hopefully it will tell us how to treat. Our oncologist said the man who found the way to test these changes is probably going to get a nobel prize for his work.
Made me think his Pca has been growing and spreading for years Cancer is so smart it figures out how to keep growing in new areas and changes so the meds to do not kill it anymore.
From what I am reading it is Pca in the liver mets but as testing is continuing they are giving new found ca cell new names. These cancer cells need different treatments and they can combine several medications to fight them. They have idenified small cell cancer cells in liver mets, if it is new or pca changed I do not know.
Dr said he wanted the biopsy in one week and today they called and told me it is not scheduled yet, it has been one week today. Carol
