What Is Adenocarcinoma?
A cancer that begins in mucus- or fluid-producing glandular cells
Can occur in organs such as the lungs, colon, rectum, pancreas, and prostate
Tends to grow slowly but may spread (metastasize) if untreated
Common Causes and Risk Factors
Smoking or long-term secondhand smoke exposure
Family history of cancer or inherited gene mutations
Chronic lung conditions (e.g., COPD) for lung adenocarcinoma
Low-fiber, high-processed-food diet for colorectal adenocarcinoma
High levels of air pollution, especially in urban areas
Signs and Symptoms
Persistent cough or wheezing (lung)
Chest pain or shortness of breath
Unexplained fatigue or unintended weight loss
Blood in stool or changes in bowel habits (colon/rectal)
Abdominal discomfort, heartburn, or fullness
Difficulty swallowing (esophageal involvement)
How Dr. Scott Diagnoses This Condition?
Dr. Scott uses a step-by-step approach:
Medical History and Physical Exam
He reviews your recent history of bleeding (surgery, trauma, GI symptoms), current medications (especially anticoagulants), and any risk factors for hemorrhage. He checks vital signs for tachycardia or hypotension and looks for signs of acute blood loss (pallor, cool extremities).
Laboratory Tests
A complete blood count measures hemoglobin and hematocrit to confirm anemia. A reticulocyte count assesses how well your bone marrow is compensating. Iron studies and a coagulation panel (PT, aPTT) help rule out other causes.
Imaging and Endoscopy
Upper or lower endoscopy identifies bleeding sources in the gastrointestinal tract.
CT angiography or tagged red-cell scans locate active bleeding in the abdomen or elsewhere.
Additional Investigations (if needed)
Stool guaiac testing for occult blood, renal and liver panels if chronic disease is suspected, and, rarely, bone marrow biopsy to evaluate marrow response in unexplained cases.
Treatment
Our Team offers a full range of care for adenocarcinoma.
1. Lifestyle and Diet Modifications
Eat more fruits, vegetables, and whole grains
Avoid smoking or get professional support to quit
Stay active with light exercise, such as walking
Practice stress relief techniques like breathing exercises, yoga, or support groups
2. Medications
Targeted therapy to block specific cancer growth pathways
Chemotherapy regimens tailored to your adenocarcinoma type
Immunotherapy to strengthen the body's natural defenses against cancer
3. Minimally Invasive or Advanced Procedures
Endoscopic removal for small rectal tumors
VATS (video-assisted thoracic surgery) for early lung adenocarcinoma
Robotic-assisted surgery for enhanced precision and faster recovery
Radiation therapy or tumor ablation when surgery isn't an option

Frequently Asked Questions
Is lung adenocarcinoma serious?
It can be, but early detection and treatment significantly improve outcomes. Dr. Scott will develop a plan tailored to your stage and overall health.
What tests does Dr. Scott suggest?
He often recommends low-dose CT scans for at-risk patients (like smokers) and colonoscopies for adults over 45, along with ultrasounds or MRIs as needed.
Can food changes help with recovery?
Yes. A diet rich in fruits, vegetables, whole grains, and lean protein supports healing, boosts immunity, and may reduce side effects from treatment.
Is robotic surgery a good option?
For many patients, yes. Robotic surgery offers smaller incisions, less pain, reduced blood loss, and a quicker return to normal activities compared to open surgery.
How long is the recovery time?
Most patients feel noticeably better within one to two weeks after minimally invasive procedures. Full recovery varies by treatment type and individual health.
What is the ICD-10 code for rectal adenocarcinoma?
The code is C20. Dr. Scott's team will include this on all documentation submitted to your insurance.
Will my insurance cover treatment?
Most major plans cover standard adenocarcinoma treatments. Our staff will verify your benefits and help you navigate any prior authorizations.
