A normal person with a thick abdominal wall usually cannot feel the sigmoid colon; a normal person with a thin abdominal wall, a fecal mass in the sigmoid colon, or a person with a tumor of the sigmoid colon may be able to feel it.
For example, for normal people, when the abdominal wall is too thick due to the accumulation of a lot of fat in the abdomen, it may not be able to feel the sigmoid colon; and if the body is thin and weak, the abdominal fat content is relatively small, the abdominal wall is thin, usually can be touched by hand to the sigmoid colon as thick as a candle, similar to the cylinder. Those who have fecal matter in the sigmoid colon can also feel hard lumps.
When a person with sigmoid colon cancer has a nodular hard mass in the abdomen as the disease gradually worsens, the sigmoid colon can also be felt at this time.
For patients with sigmoid colon cancer, they should follow the doctor’s instruction and go to regular hospitals for diagnosis and treatment in time.
