Cancer Treatment Options: A Comprehensive Overview

Optimal cancer therapy is personalized, based on tumor type, stage, molecular profile, patient health, and preferences. A multidisciplinary tumor board typically designs the plan.

Major Modalities

1. Surgery: Primary resection for localized solid tumors; often curative in early stages.
2. Radiation Therapy: High‑energy beams (photons, protons) damage DNA; used as definitive, adjuvant, or palliative treatment.
3. Chemotherapy: Cytotoxic drugs targeting rapidly dividing cells; systemic; neoadjuvant, adjuvant, or palliative.
4. Targeted Therapy: Small molecules or antibodies against specific oncogenic drivers (e.g., EGFR, HER2, BCR‑ABL, ALK).
5. Immunotherapy: Checkpoint inhibitors (PD‑1/PD‑L1, CTLA‑4), CAR‑T cells, cancer vaccines—harness immune system.
6. Hormone Therapy: For hormone‑receptor‑positive breast/prostate cancers (anti‑estrogens, aromatase inhibitors, androgen deprivation).
7. Stem Cell Transplant: Autologous/allogeneic rescue after high‑dose chemo for hematologic malignancies.

Emerging Approaches

• Antibody‑drug conjugates, bispecific antibodies, oncolytic viruses, microbiome modulation.

Follow‑Up

Regular imaging, tumor markers, and clinical assessment to monitor response, detect recurrence, and manage late effects.
