Adenocarcinoma is a type of cancer that originates in glandular cells'those that produce mucus or other fluids. It can develop in various organs such as the lungs, colon, pancreas, and prostate. When these cells begin to grow uncontrollably, they form malignant tumors.
He reviews your personal and family medical history, symptoms (like cough, weight changes or abdominal pain), lifestyle factors and any inherited risks.
Depending on the tumor location, he performs bronchoscopy, colonoscopy or endoscopic ultrasound to visualize lesions and obtain tissue samples for histologic confirmation.
Pathology analysis classifies the adenocarcinoma subtype. Advanced molecular profiling (EGFR, KRAS, ALK, MSI) and special stains identify rare forms'such as signet ring cell adenocarcinoma to guide targeted therapies.

Adenocarcinoma is a type of cancer that starts in glandular (mucus- or fluid-producing) cells, often occurring in the lungs, colon, pancreas, or prostate.
When detected early, lung adenocarcinoma can often be cured with surgery and targeted treatments, sometimes combined with chemotherapy or immunotherapy.
The ICD-10 code for primary malignant neoplasm of the rectum (including rectal adenocarcinoma) is C20.
Signet ring cell adenocarcinoma is a rare, aggressive subtype in which cancer cells contain large mucin vacuoles that push the nucleus to one side, resembling a signet ring.
While a diet rich in fruits, vegetables, and whole grains can lower your risk, it cannot completely prevent adenocarcinoma. Regular screening and healthy lifestyle habits help most.
Most patients go home within 1-3 days after laparoscopic or robotic surgery and fully recover in about 2-4 weeks, depending on individual health factors.
Diagnosis typically involves chest imaging (CT or PET scans) followed by a tissue biopsy, often obtained via bronchoscopy or needle biopsy, to confirm cancer type.
Yes. Many Houston patients consult with Dr. Chadha for a second opinion before starting treatment to ensure they have the most comprehensive care plan.
