Patient discussion about positive

Q. What she should do, if found positive? my wife who is 31 years, had breast cancer history in her family and I have advised her to have a test. She will have her test done next week. What she should do, if found positive?

A. I think you must pray that she is not positive, but if found positive let the doctor start the treatment and she should cooperate with doctor. She needs to learn about her problem and also the ways to cope them, like by having good diet and fitness, which she would require when the treatment or surgery will be done. Thanks ....and hope she is not positive…

Q. The HIV test came back POSITIVE! My very close friend 'Demonte'. One day in December as he was returning from a business trip, his wife met him at the airport with terrible news. During a routine pregnancy check up, her doctor had administered an HIV test along with other blood-work. The HIV test came back POSITIVE! The doctor wanted to begin administering drugs immediately but the cost of these drugs here when compared to their family income was prohibitive. I helped him with some of my savings. He already sold his favorite sentimental car to save his precious wife. Now i want to know is there any NATURAL medicine to cure this? Hope it costs less and available.

A. there are no effective natural remedy for HIV. the medications are very hard ones that try to control the virus from spreading (cannot eliminate it though). no herbal remedy or nutrition change will do that.

Q. is her2 positive more agressive than her2 negative? i know someone with her2 positive breast cancer and her doctor said it was more difficult to detect upon its return if it came back i want to know if it is true and what can she do to detect it earlier

A. Over-expression of her2/neu, a specific molecule in the breast cancer cell is indeed considered to convey worse prognosis, and suggest the need for chemotherapy and immunotherapy with Herceptin. However, the decision is much more complicated and should be made on case by case basis after consulting a professional.
