Is Mould Bad For People With Asthma?

I work in an office where mould has been discovered within the walls. It would have been present for quite some time; at least in excess of 3 years or more. I have juvenile diabetes, had borderline stage 4 colon cancer and surgery/kemo in 2011 and was diagnosed with asthma approximately 4 years ago. I have developed severe allergies to scents, grasses, flowers/plants, foods, etc in the past number of years. I am 63 years of age and thankfully cancer free since my surgery and treatment in 2011/12. Are any of these conditions a result of or exasperated by the presence of mould in a place I work 8 hours per day. Trying to get it removed as soon as possible. At least 3 of my co-workers suffer from various symptoms such as respitory problems as well as headaches and lethargy.
