Kinda worried for my health

So long story short I’ve been working for a company that I do sandblasting and water honing everyday for and I never use a mask and I’ve worked there going on two years. I do have half masks and full face masks available but have a beard so idk if they work or not. Can I fit them properly with a beard? Not being truly educated about silica dust and how dangerous it actually is and already having some health issues with my pancreas unrelated to my job, I’m worried I’ll get silicosis and have noticed a slight tightness of breathing especially when exercising or doing brisk activity but do have a history of smoking but have quit 4 months ago. I do plan to get checked for it but was recently in the hospital 4 months ago with ct scans for pancreas and they didn’t say anything about that and said my oxygen levels are good
