PPT On Colorectal Cancer
Download
Presentation Transcript:
1. Colorectal Cancer (CRC)
Epidemiology, Risk Factors Symptoms, Stages, Therapy Molecular Biology & Pathology Screening
2. What is Cancer?
A group of 100 different diseases The uncontrolled, abnormal growth of cells Cancer may spread to other parts of the body
3. What is Colorectal Cancer?
Third most common type of cancer and second most frequent cause of cancer-related death A disease in which normal cells in the lining of the colon or rectum begin to change, grow without control, and no longer die Usually begins as a noncancerous polyp that can, over time, become a cancerous tumor
4. EPIDEMIOLOGY
one of the most common cancers in the world US:4th most common cancer (after lung,prostate, and breast cancers) 2nd most common cause of cancer death(after lung cancer) 2001:130,000 new cases of CRC 56,500 deaths caused by CRC
5. Risk factors for CRC
Age Adenomas, Polyps Sedentary lifestyle, Diet, Obesity Family History of CRC Inflammatory Bowel Disease (IBD) Hereditary Syndromes (familial adenomatous polyposis (FAP))
6. Development of CRC
result of interplay between environmental and genetic factors Central environmental factors: diet and lifestyle 35% of all cancers are attributable to diet 50%-75% of CRC in the US may be preventable through dietary modifications
7. Symptoms associated with CRC
weight loss
loss of appetite
night sweats
fever
rectal bleeding
change in bowel habits
obstruction abdominal pain &
mass iron-deficiency anemia
8. Staging of CRC
TNM system Primary tumor (T) Regional lymph nodes (N) Distant metastasis (M)
9. Therapy
Surgical resection the only curative treatment Likelihood of cure is greater when disease is detected at early stage Early detection and screening is of pivotal importance
10. For more info please refer our PPT.
Thanks.
