My mother-in-law was taken to the ER today w/ bleeding from the rectum and w/bowel movements, weight loss, loss of energy and left upper quandrant pain. Her CT showed a "irregularity" of the colon and something on her spleen a possible growth. Irregularity?? Any ideas? Her father passed from colon cancer. Anyone with knowledge of the connection between the colon and spleen. I'm fearing cancer. Anyone with knowledge of colon cancer? If so, could it also effect the spleen? I welcome all responses. Just need some kind of answer before tomorrow. Thank you all.
