A cecal mass is a lump or volume of tissue in the cecum, or beginning of the large intestine. While not always the case, cecal masses can be found in those with cecum cancer, notes About.com.
While a cecal mass can bleed, typically one will not see the blood as by the time it passes through all the intestines it is unable to be detected by sight. Cecal masses can be removed and tested for malignancy after diagnostic testing. About.com explains that masses in this area may not be felt by the individual, but may be detected through a colonoscopy, which can examine the cecum.
