Understanding Cancer Treatment
Cancer treatment has evolved dramatically over the past decades. Today, oncologists can choose from a wide array of treatment modalities - often using multiple approaches in combination to achieve the best outcomes. The right treatment plan depends on many factors including cancer type, stage, molecular characteristics, and your overall health and preferences.
Our comprehensive treatment guides explain how each modality works, what to expect during treatment, how to manage side effects, and what questions to ask your oncology team.
Chemotherapy
Systemic TreatmentUses powerful drugs to destroy cancer cells throughout the body. Remains a cornerstone of cancer treatment for many types.
- Works by targeting rapidly dividing cells
- Can be curative, adjuvant, or palliative
- Given IV, oral, or by injection
- Multiple drug classes with different mechanisms
- Side effects manageable with modern supportive care
Immunotherapy
Systemic TreatmentHarnesses the power of your immune system to fight cancer. Has revolutionized treatment for many cancer types.
- Checkpoint inhibitors (PD-1, PD-L1, CTLA-4)
- CAR-T cell therapy
- Cancer vaccines
- Monoclonal antibodies
- Can provide durable long-term responses
Targeted Therapy
Systemic TreatmentDrugs that target specific proteins or genes in cancer cells, blocking their growth and spread.
- Requires molecular testing of tumor
- Targets specific mutations or proteins
- Often less toxic than chemotherapy
- Examples: EGFR, ALK, HER2, BRAF inhibitors
- Precision medicine approach
Radiation Therapy
Local TreatmentUses high-energy rays or particles to destroy cancer cells in specific areas of the body.
- External beam radiation (EBRT)
- Brachytherapy (internal radiation)
- Stereotactic radiosurgery (SRS, SBRT)
- Often combined with surgery or chemotherapy
- Advanced techniques minimize damage to healthy tissue
Palliative Care
Supportive TreatmentSpecialized care focused on relieving symptoms, managing side effects, and improving quality of life at any stage of cancer.
- Appropriate from diagnosis onward, not only end of life
- Works alongside active cancer treatment
- Addresses pain, fatigue, nausea, and emotional wellbeing
- Supports caregivers and families
- Delivered by a multidisciplinary team
BCG Therapy
Local ImmunotherapyIntravesical Bacillus Calmette-Guérin — a long-established immunotherapy used primarily for non-muscle-invasive bladder cancer.
- Delivered directly into the bladder
- Standard of care for intermediate- and high-risk NMIBC
- Induction course followed by maintenance schedule
- Reduces recurrence and progression
- Distinct side-effect profile from systemic therapy
Clinical Trials
Research & AccessResearch studies testing new treatments or new uses of existing treatments. May provide access to cutting-edge therapies.
- Phases I, II, III, and IV trials
- Access to newest treatments
- Close monitoring and care
- Help advance cancer research
- Appropriate for many patients, not just last resort
Multimodal Treatment Approach
Most cancer treatment today involves multiple modalities used together or in sequence:
- Neoadjuvant: Treatment given before surgery to shrink tumors
- Adjuvant: Treatment given after surgery to eliminate remaining cancer cells
- Concurrent: Two or more treatments given at the same time (e.g., chemoradiation)
- Sequential: Different treatments given one after another
- Maintenance: Lower-intensity treatment to keep cancer in remission
Choosing the Right Treatment
Your oncologist will recommend treatment based on:
- Cancer type and location - Different cancers respond to different treatments
- Stage of disease - Localized vs. metastatic affects treatment approach
- Molecular characteristics - Genetic mutations, biomarkers, receptor status
- Your overall health - Performance status, comorbidities, organ function
- Treatment goals - Curative intent vs. palliative care
- Your preferences - Quality of life considerations, personal values
Don't hesitate to get a second opinion or ask questions. Understanding your treatment plan empowers you to be an active participant in your care.
