I have a dear cat who's cancer has returned,and I lost a dear cat to cancer early this year,and I now have found I have a thick lining of the womb,have to have biopsy but not looking forward to biopsy any advice from others who've had and also people whose animals have had cancer,don't you just get so angry this thing still causes death and loss.i wish I was brighter like really academic but I'm not academic at all,ie my love's were art and sport.i wish I was brighter to know how to fight this awful ugly disease.when will academia solve this  ancient disease,or make all cancers treatable ,ie so you can live,live being the word a normal life expectancy with it.im not worried to much,abit I may have some cancer cells in lining of womb,but I know current treatment for the human animal holds a much better prognosis for managing cancer or longevity should it be the worst stage.but animals like my dear Queenie cat gives them less time than say if I have biospy and says womb cancer.i want to know when will pet medicine be as effective in times of life longevity for animals.ie it's great how vets try to make a animal comfortable with cancer,but it's time like human medicine we fight,or vets fight as hard as there owners to do to stop cancer killing.
