Rectal cancer is a type of cancer that affects the rectum, the last part of the large intestine. The spelling of rectal cancer uses the IPA phonetic transcription /ˈrɛktəl ˈkænsər/. The word "rectal" is pronounced with a stressed syllable on the second vowel sound /e/ and the second syllable is pronounced with a schwa sound /ə/. The word "cancer" is also pronounced with a stressed syllable on the second vowel sound /æ/ and the final syllable is pronounced with a weak syllable on the /ər/ sound. Any rectal bleeding or discomfort should be checked by a doctor.
Rectal cancer refers to the growth of cancerous cells in the tissues lining the rectum, which is the final segment of the large intestine located just above the anus. This type of cancer typically originates from benign polyps or abnormal growths that form in the inner lining of the rectum and can steadily progress into malignant tumors over time if left untreated.
The symptoms of rectal cancer can vary depending on the stage of the disease, and may include changes in bowel habits (such as persistent diarrhea or constipation), blood in the stool, abdominal pain, cramping, fatigue, weight loss, or a feeling of incomplete bowel movement. However, these symptoms are not exclusive to rectal cancer and can be attributed to other gastrointestinal conditions, making it important to consult a healthcare professional for accurate diagnosis.
Diagnosis usually involves a combination of physical exams, digital rectal exams, imaging tests (such as colonoscopy or sigmoidoscopy), and biopsies to determine the presence and extent of cancer. The treatment of rectal cancer depends on various factors including the stage of the disease, the size and location of the tumor, and the overall health of the patient. Treatment options may include surgery to remove the tumor and nearby lymph nodes, radiation therapy, chemotherapy, targeted therapy, or a combination of these approaches.
Regular screenings, such as colonoscopies, are essential for early detection of rectal cancer, as it increases the chances of successful treatment and improves long-term outcomes. Additionally, maintaining a healthy lifestyle with a balanced diet, regular physical activity, and avoiding risk factors such as tobacco use and excessive alcohol consumption can help reduce the risk of developing rectal cancer.
The word "rectal cancer" has a straightforward etymology. First, let's break down the word into its parts:
1. Rectal: The word "rectal" comes from the Latin word "rectum", which means "straight" or "proper". It refers to the last portion of the large intestine, connecting to the anus.
2. Cancer: The term "cancer" originates from the Latin word "cancer", meaning "crab". The Greek physician Hippocrates used this word to describe some tumors he observed, as they seemed to extend their limbs like a crab. Over time, "cancer" became the term commonly used to refer to malignant growths or tumors.
When these two words are combined, "rectal cancer" specifically refers to cancerous growths within the rectum.
