H Pylori

Was wondering if I could ask if anyone who knows or been diagnosed with stomach cancer have H Pylori or ever have! I've recently been diagnosed and my nan and 2 her sisters had stomach cancer and I'm so worried. Doctors tell me it's not a bad bacteria or connected only if been there a long long time but I Jsut wanted to find this for myself. I'm only 37 with 3 children so it's worrying me

 

thank you
