How Dr. Scott Diagnoses This Condition?
Dr. Scott uses a step-by-step approach:
Medical History and Physical Exam
He reviews your history of epigastric discomfort, changes in bowel habits, weight loss, bleeding, family history of colon cancer, dietary patterns and lifestyle risk factors.
Laboratory Tests
Complete blood count to detect anemia from chronic bleeding.
CEA (carcinoembryonic antigen) tumor marker to help assess cancer activity.
Stool occult blood test to identify hidden blood loss.
Endoscopic Evaluation
Colonoscopy to visualize the colon lining, locate tumors and obtain biopsies.
Upper endoscopy (EGD) when epigastric pain is prominent, to rule out concurrent gastric or duodenal issues.
Imaging Studies
Contrast-enhanced CT or MRI of the abdomen and pelvis to stage the tumor and look for spread.
Endoscopic ultrasound in select cases to evaluate depth of invasion and nearby lymph nodes.
Advanced Testing (if needed)
Diagnostic laparoscopy or PET-CT may be used for challenging cases to guide treatment planning and staging.

Frequently Asked Questions
What is the survival rate for colon tumors?
When found early, the five-year survival rate is over 90 percent. Later stages have lower rates but still benefit from comprehensive treatment.
What does a CA colon tumor marker test show?
It measures specific proteins in your blood. Elevated levels may suggest colon cancer or help monitor how well treatment is working.
What stage is a 7 cm colon tumor?
A 7 cm tumor is commonly stage II or III. The exact stage depends on whether cancer cells have reached nearby lymph nodes.
What stage is a 10 cm colon tumor?
A 10 cm tumor is often stage III or IV, especially if it has grown through the colon wall or spread to lymph nodes or other organs.
When should I get a colonoscopy?
If you're over 50, have a family history of colon cancer, or notice symptoms like blood in your stool, schedule a colonoscopy promptly.
Can changing my diet help prevent colon tumors?
Yes. Adopting a high-fiber, plant-rich diet and reducing red meat and processed foods-combined with regular exercise-can lower your risk.
Are less invasive surgeries safe for colon tumors?
Yes. Minimally invasive approaches-such as laparoscopic or robotic-assisted surgery-are safe and often lead to shorter hospital stays and faster recovery when performed by experienced surgeons.
