Cancer Treatment Overview: No Single Cure, Many Modalities

Cancer Treatment Is Highly Individualized

There is no universal "primary cure" for cancer. The optimal approach depends on:

• Cancer type, subtype, and molecular markers
• Stage (extent of spread)
• Patient age, comorbidities, preferences
• Goal: curative vs. palliative

Major Treatment Categories

Modality	Mechanism	Typical Use
Surgery	Physical tumor removal	Localized solid tumors; diagnostic/staging
Radiation therapy	DNA damage via ionizing radiation	Local control; adjuvant; palliative
Chemotherapy	Cytotoxic drugs targeting dividing cells	Systemic disease; neoadjuvant/adjuvant
Targeted therapy	Inhibits specific molecular drivers (e.g., EGFR, HER2, BCR-ABL)	Biomarker-selected cancers
Immunotherapy	Activates immune system (checkpoint inhibitors, CAR-T)	Melanoma, lung, lymphoma, etc.
Hormone therapy	Blocks hormone synthesis/action	ER⁺ breast, prostate cancer
Stem cell transplant	Rescues bone marrow after high-dose chemo	Leukemias, lymphomas, myeloma

Multimodal Approach

Most curative regimens combine modalities (e.g., surgery → adjuvant chemo ± radiation). Multidisciplinary tumor boards tailor plans.

Emerging Frontiers

• Precision oncology (NGS-guided therapy)
• Bispecific antibodies, antibody-drug conjugates
• Microbiome modulation, oncolytic viruses

Discuss your specific diagnosis with an oncologist to understand recommended options and clinical trial eligibility.
