Duodenal ulcers. Is very nervous now.

Hi, 20 days ago my father has bloating, abdomen discomfort and not able to pass stool, consulted a dr and done tests, in cbc his haemo was 6.7 and rbc was also less and occult blood in stool was +, so dr suggested endoscopy and blood transfusion, after 2 units of blood his haemo becomes 10.9 and occult blood absence  in stool, also other parameters in full body blood tests were normal, then 3 days ago we went for endoscopy, there is a chronic duodenal ulcer and h pyloric + and dr took biopsy, it's result didn't came yet. 2 years ago similar issues he was facing only blood was not in stool, then also we went for endo, CT scan and biopsy at that chronic non specific Duodentisis with brunner's gland hyperplasia with no evidence of malignancy and tb, in CT scan everything were normal, now tell me for current situation and endoscopy report what are the malignancy chances, dr told let the biopsy report come, so what are the chances of malignancy, actually my family is very nervous now .
