Definition:
Rectal neoplasm is a form of colorectal cancer affecting the rectum. Because it has no early symptoms, the disease is frequently under-diagnosed.
When symptoms do occur, both the symptoms and the diagnostic tests required to confirm the diagnosis are considered embarrassing by most patients.
However, early diagnosis of rectal neoplasm is crucial because colorectal cancer can prove ultimately fatal.
Diagnosis:
To diagnose rectal neoplasm, there are some tests that can be done to examine the rectum and colon.
A fecal occult blood test can be done to check the patient's stool for microscopic blood. A digital rectal exam can also help identify indicative lumps in the patient's rectum. In addition, a series of x-rays known as barium enema can be done to examine the lower gastrointestinal tract.
Other related diagnostic tests include sigmoidoscopy, colonoscopy, and of course, a biopsy to determine signs of cancer.
Symptoms and Signs:
Some symptoms of rectal neoplasm include passage of blood in the stool, gastrointestinal bleeding, constipation, altered bowel habits, and diarrhea.
General discomfort in the abdomen (such as gas pains, bloating, fullness, and cramps), unexplained weight loss, severe exhaustion, and vomiting are also indicative of rectal neoplasm.
