How Does Chemotherapy Work to Fight Cancer?

Cancer treatment has advanced significantly over the years, with chemotherapy being one of the most effective and widely used methods to combat various types of cancer. At Cancer Care Pune Clinic, a leading cancer treatment clinic in PCMC and Pune, patients receive expert care under the guidance of Dr. Jagdish Shinde. Chemotherapy plays a crucial role in managing and treating cancer by targeting and destroying cancerous cells, preventing their spread, and reducing tumor size. But how exactly does chemotherapy work? Let’s explore its mechanisms, types, and effects on the body.

Understanding Chemotherapy

Chemotherapy, often referred to as “chemo,” is a treatment that uses powerful drugs to kill rapidly dividing cancer cells. Since cancer cells grow and multiply uncontrollably, chemotherapy helps in disrupting this process. Unlike surgery or radiation, which target specific areas, chemotherapy works systematically, meaning it affects cancer cells throughout the body.

How Chemotherapy Targets Cancer Cells

Chemotherapy drugs interfere with the cancer cell cycle, preventing them from growing and multiplying. These drugs typically work by:

1. Damaging Cancer Cell DNA – Many chemotherapy drugs target the DNA or RNA of cancer cells, preventing them from replicating. Without proper replication, the cells die or become incapable of multiplying.
2. Inhibiting Cell Division – Some chemotherapy drugs stop cancer cells from dividing and growing, disrupting their lifecycle and leading to their death.
3. Blocking Essential Nutrients – Certain chemotherapy treatments cut off the supply of nutrients cancer cells need to thrive, leading to their destruction.

While chemotherapy primarily targets cancer cells, it can also affect some healthy cells that divide quickly, such as those in the hair, digestive system, and bone marrow, which leads to common side effects.

Types of Chemotherapy

Chemotherapy is categorized based on how the drugs work against cancer. Some common types include:

1. Alkylating Agents – These drugs damage the DNA of cancer cells, preventing them from reproducing. They are used for various cancers, including leukemia, lymphoma, and breast cancer.
2. Antimetabolites – These drugs interfere with cancer cell metabolism, stopping their growth. Examples include methotrexate and 5-fluorouracil.
3. Anti-tumor Antibiotics – These drugs prevent cancer cells from dividing by disrupting their DNA. Examples include doxorubicin and mitomycin.
4. Mitotic Inhibitors – These drugs block cell division, stopping cancer cells from multiplying. They are often used for breast, lung, and blood cancers.
5. Targeted Therapy – A more advanced form of chemotherapy that specifically targets cancer cells while sparing healthy cells, leading to fewer side effects.

How Chemotherapy Is Administered

Chemotherapy can be delivered in various ways, depending on the type and stage of cancer:

• Intravenous (IV) Infusion – The most common method, where drugs are delivered directly into the bloodstream.
• Oral Chemotherapy – Pills or capsules taken at home, allowing for greater convenience.
• Injection – Administered directly into the muscle, under the skin, or into a specific part of the body.
• Topical Application – Used for certain skin cancers, where a chemotherapy cream is applied.

Side Effects of Chemotherapy

Since chemotherapy affects rapidly dividing cells, it can impact healthy cells as well, leading to side effects such as:

• Fatigue
• Nausea and vomiting
• Hair loss
• Weakened immune system
• Loss of appetite
• Neuropathy (nerve damage causing pain or tingling)
• Anemia

At Cancer Care Pune Clinic, Dr. Jagdish Shinde ensures that chemotherapy treatment is personalized, with supportive care to manage side effects and improve patients’ quality of life.

Effectiveness of Chemotherapy

Chemotherapy is used in different ways depending on the type and stage of cancer:

• Curative Chemotherapy – Aims to completely eradicate cancer.
• Adjuvant Chemotherapy – Given after surgery or radiation to destroy any remaining cancer cells.
• Neoadjuvant Chemotherapy – Administered before surgery to shrink tumors.
• Palliative Chemotherapy – Used to relieve symptoms and improve quality of life in advanced cancer cases.

Combining Chemotherapy with Other Treatments

In many cases, chemotherapy is used in combination with other treatments such as:

• Surgery – To remove tumors and follow up with chemo to kill residual cancer cells.
• Radiation Therapy – To enhance the effectiveness of cancer treatment.
• Immunotherapy – Helps the body’s immune system fight cancer more effectively.

Advancements in Chemotherapy

Newer chemotherapy drugs and targeted therapies have significantly improved cancer treatment outcomes. Some advancements include:

• Personalized Chemotherapy – Tailored treatments based on a patient’s genetic profile.
• Less Toxic Drugs – Reducing side effects while maintaining effectiveness.
• Immunotherapy Combinations – Enhancing the body’s natural defense against cancer.
