I have 5 relatives diagnosed with cancer, and only two still alive.
My 1st aunt (mother's side) died in about one year after diagnosis of breast cancer. When she die, I was only about one years old.
My 4th aunt (mother's side) diagnosed with uterus cancer after give birth to my cousin more than 10 years ago. Luckily, the cancer was found early. She have her uterus removed immediately, and still alive today.
My grandfather (dad's side) died from lung cancer when I was about 13. He never smoke, none of my family members smoke. Doctor said he can't have operation or any treatment because of old age.
My father died from pancreatic cancer about 3 years ago. In 2004, he was diagnosed with this disease and have large part of pancreas removed. He do chemotherapy. About two years later, the cancer relapse and spread. He died after a few months. Doctor said my dad can life about 2 and half years already considered lucky, as most of the patient with this cancer cannot live more than one year.
My grandmother (mother's side) diagnosed with lymphoma. She is still alive but she never believe that she has this disease. She is stubborn, doesn't believe the doctor. She refuse for treatment.
Nowadays, even babies also get cancer.
However, if you or your family having cancer, don't follow my grandmother. Just follow what the doctor said, do whatever treatment suggested by doctor. Good luck.
Do not have blind faith in doctors. Dr. Ray Strand said that.
