Cancer Prevention

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Endoscopic Procedures I: Esophagogastroduodenoscopy

Endoscopic Procedures I: Esophagogastroduodenoscopy

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Endoscopic Procedures II: Colonoscopy

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Endoscopic Procedures III: Video Capsule Endoscopy

Endoscopic Procedures III: Video Capsule Endoscopy

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers, unexplained...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Summary

Polypectomy significantly reduces colon carcinoma rates by 66%. This procedure involves removing polyps, which are growths that can develop into cancer, particularly adenomas.

Area of Science:

Gastroenterology
Endoscopic Surgery
Oncology

Context:

Colon carcinoma often arises from adenomatous polyps, following the adenoma-carcinoma sequence.
Polypectomy is a key intervention for preventing colon cancer development.
Endoscopic techniques are crucial for diagnosing and treating pre-cancerous lesions.

Purpose:

To detail the efficacy of polypectomy in reducing colon carcinoma incidence.
To describe endoscopic methods for polyp removal, including snare polypectomy and strip biopsy.
To highlight the challenges and management of flat colorectal neoplasms.

Summary:

Polypectomy effectively reduces colon carcinoma rates by 66%.
The majority of colon cancers develop from adenomas, necessitating their removal.
Various endoscopic techniques, including snare removal, strip biopsy, and piecemeal resection, are employed for different polyp types.
Special attention is given to flat neoplasms due to their potential for submucosal invasion.

Impact:

Demonstrates a significant reduction in colon cancer incidence through routine polypectomy.
Provides insights into endoscopic management strategies for colorectal polyps and early-stage cancers.
Emphasizes the importance of adhering to established guidelines, such as those from the Japanese Society of Gastroenterological Endoscopy, for optimal patient outcomes.
