Lymphoma is a type of cancer that affects the lymphatic system. This system includes your lymph nodes, spleen, and other parts that help fight infection. In lymphoma, certain white blood cells (called lymphocytes) grow abnormally. These cells can build up and spread to other areas if not treated early.
Dr. Chadha reviews your symptoms, risk factors, and palpates lymph nodes for swelling or tenderness.
Complete blood count and immune marker panels help detect abnormal lymphocyte levels and rule out other causes.
CT scans, ultrasound or PET/CT are used to identify enlarged lymph nodes or organ involvement.
A needle-guided or endoscopic tissue sample confirms the presence and type of lymphoma cells.
In select cases, a bone marrow biopsy determines whether lymphoma has spread to the marrow.

Lymphoma is a cancer that starts in white blood cells called lymphocytes, affecting the lymphatic system including lymph nodes, spleen, and other infection-fighting parts.
Common warning signs include swollen lymph nodes in the neck, underarms, or groin; fevers and night sweats; fatigue; unexplained weight loss; itchy skin or red spots; and digestive issues like belly pain or nausea.
Lymphoma is broadly grouped into Hodgkin lymphoma (classic and nodular types) and non-Hodgkin lymphoma (including large B-cell, follicular, mantle cell, T-cell, and other subtypes).
Dr. Chadha's diagnostic process includes a medical history and physical exam, blood tests, imaging scans (CT, ultrasound, PET/CT), a tissue biopsy (needle or endoscopic), and sometimes a bone marrow test.
Treatment may involve chemotherapy, immunotherapy, targeted therapy, antiviral medicine (if linked to an infection), radiation therapy, endoscopic or laparoscopic procedures, and stem cell or bone marrow transplant, combined with lifestyle support.
Yes. Eating nutritious meals with fruits, vegetables, and lean protein helps support your body during treatment and recovery.
Many cases can be brought into remission-especially when treatment begins early.
Duration varies by lymphoma type and stage. Some patients complete treatment in a few months; others may need longer, individualized plans.
No referral is required. You can call GastroDoxs directly to schedule an appointment or ask your primary care doctor to refer you.
Dr. Chadha treats patients at GastroDoxs clinics in Montrose and Memorial City, Houston, Texas.
