Lower Abdominal Hardness: Symptoms and Cancer Concerns

Lower abdominal mass?

Hello! Recently, I have noticed a hard mass located about two centimeters above my lower abdominal hip bone.
It is difficult to feel when standing, but I can easily palpate it when sitting down.
The mass becomes more prominent when I have the urge to defecate, and it feels less noticeable after a bowel movement.
Sometimes, there is a slight tenderness when I press on it.
During my last abdominal ultrasound, I asked the doctor to examine it, and he suggested it might be fat, but it seemed he did not find anything conclusive.
Additionally, I have a small lump near my anus that resembles a mung bean, which sometimes itches and hurts, especially during bowel movements.
My family has a history of colorectal and rectal cancer.
I would like to know if the symptoms I described could potentially indicate cancer or if they are simply early warning signs.
Thank you.

Hello, generally speaking, once abdominal tumors or masses appear, they do not shrink or disappear.
Therefore, the hard or protruding object that you feel may be a distended section of the intestine, which can subside after the distention resolves.
Of course, subcutaneous structures like lipomas may feel subtle when they are smaller.
Additionally, ultrasound is not effective for visualizing the gastrointestinal tract, and diagnosing gastrointestinal issues with ultrasound is quite challenging.
As for a family history of colorectal cancer, it is significant, and screening is recommended for individuals over 40 years old.
However, you are only 27.
Finally, it is advisable to consult a gastroenterologist for further evaluation and treatment.
Wishing you good health, Dr.

More Info

It's understandable to be concerned about any unusual symptoms, especially given your family history of colorectal cancer. The presence of a hard mass in the lower abdomen, particularly one that is more noticeable when sitting or during bowel movements, can be indicative of several conditions, some benign and others more serious.

Firstly, the hard mass you are feeling could be related to a few different factors. It might be a palpable structure such as a stool impaction, which can occur if there is constipation. This can lead to a feeling of fullness or hardness in the abdomen. Another possibility is that it could be a benign growth, such as a lipoma (a fatty tumor), which can sometimes be mistaken for more serious conditions. However, the fact that it becomes less noticeable after a bowel movement suggests that it may be related to bowel contents or pressure changes in the abdomen.

Regarding the small lump near the anus that resembles a green bean and causes itching or pain, this could potentially be a hemorrhoid or a skin tag. Hemorrhoids are swollen veins in the lower rectum and anus that can cause discomfort, especially during bowel movements. Given your family history of colorectal cancer, it is essential to monitor these symptoms closely.

The family history of colorectal cancer is significant. Individuals with a family history of colorectal cancer are at a higher risk, which is why regular screenings are recommended, especially if you are over 40 years old or have symptoms that could indicate a problem. Although you are currently 27, it might be prudent to discuss your symptoms and family history with a gastroenterologist, who can recommend appropriate screening or diagnostic tests, such as a colonoscopy.

In terms of whether these symptoms could be early signs of cancer, it is important to note that not all lumps or changes in bowel habits indicate cancer. However, any persistent changes, especially in the context of a family history of cancer, warrant further investigation. Symptoms such as unexplained weight loss, changes in bowel habits, or blood in the stool should be taken seriously and evaluated by a healthcare professional.

In conclusion, while the symptoms you describe may not necessarily indicate cancer, they should not be ignored, especially given your family history. It is advisable to consult with a healthcare provider who can perform a thorough evaluation, possibly including imaging studies or a referral for a colonoscopy, to rule out any serious conditions. Early detection is key in managing any potential health issues effectively.
