Hi, I am currently living in UK and my family is in India. My father has a cancer history of more than 18 years. The symptoms started showing up in 1996 and the doctor did not advise for a scan that time. Later, he was detected with a large cancerous tumor on his left kidney and the entire kidney was taken out. The doctors advised him not to take Cigarettes as he was a chain smoker but he continued taking it at a reduced quantity for 10 years post operation and later in Nov, 2012 he was detected with one metastatic cancer tumor in his bran and several small nodules in his lungs and supra renal gland. The doctors prescribed him to take steroids before operation and post operation has has gone through complete remission of cancer. All nodules melted away on its own. However, he started showing symptoms of gastric ulcer. He started feeling racing heart due to anemia and he had black tarry stool and black vomiting in the month of August 2014. He quickly recovered and he was stable. But, he started having spicy food after a month. The symptoms came back strongly last December. Within a month, he recovered again. However, the symptoms keep coming these days and he is loosing his weight. Sometimes, he will be alright and start gaining weight and after 4 weeks the symptoms will come back again. There were 3-4 recurrences within a span of 6 months. Please advise.
