Granuloma on incision area after 6 months - Should I be worried? (Photos)

I have a granuloma which it started oozing through a small little hole and on day 2 after I started squeezing out the fluid ,which was only like clear fluid with just a bit of blood. I cleaned it but then I noticed that there was something else like part of my meat with the whitish looking thing coming out . I tried cleaning it But then I got scared. I contacted my surgeon he said just clean it out but then I told him what I seen then he just responded to go to the ER!
