Chemotherapy is a medical treatment that uses powerful drugs to destroy or slow down the growth of cancer cells. It is a common approach in cancer treatment and can be used alone or in combination with other therapies such as surgery or radiation therapy.
Chemotherapy drugs can be administered through different methods, including oral pills, injections, or infusion into a vein.

The main goal of chemotherapy is to target and kill rapidly dividing cancer cells throughout the body. However, since chemotherapy drugs can also affect healthy cells that divide quickly, it can lead to various side effects.
The specific side effects experienced by a patient can vary depending on the type and dose of chemotherapy drugs used, as well as individual factors.
The choice of chemotherapy regimen and duration of treatment depend on factors such as the type and stage of cancer, the patient’s overall health, and the treatment goals.
Chemotherapy can be given in cycles, with each cycle consisting of a treatment period followed by a rest period to allow the body to recover. The treatment duration can vary from a few weeks to several months.

Chemotherapy Introduction
Chemotherapy is primarily used to treat cancer. It can be employed as the primary treatment, known as primary chemotherapy, to shrink tumors before surgery or radiation therapy. It can also be used as adjuvant therapy after surgery to kill any remaining cancer cells or as palliative therapy to relieve symptoms and slow the progression of advanced cancer.

How It Works
Chemotherapy drugs interfere with the cell division process, targeting and killing rapidly dividing cells, including cancer cells. They work by damaging the DNA or other vital components within the cells, preventing them from dividing and growing. Since cancer cells divide more rapidly than normal cells, they are more susceptible to the effects of chemotherapy.
However, some healthy cells, such as those in the bone marrow, digestive tract, and hair follicles, also divide rapidly and can be affected by chemotherapy, leading to side effects.

Chemotherapy Treatment
- Preparing for Treatment: Before starting chemotherapy, various preparations may be necessary. This could involve baseline tests to assess organ function, blood counts, and overall health. The oncologist will discuss the treatment schedule, potential side effects, and supportive care measures to manage them. They will also provide instructions regarding medications, dietary guidelines, and lifestyle adjustments during treatment.
- Administration of Chemotherapy: Chemotherapy drugs can be administered through different methods, depending on the specific treatment plan. The most common methods include:
- Intravenous (IV) Infusion: The drugs are delivered directly into a vein through a needle or catheter, often in an outpatient clinic or hospital setting. The infusion can take several hours, and the frequency and duration of treatment cycles depend on the prescribed regimen.
- Oral Medication: Some chemotherapy drugs are available in the form of pills or capsules, which can be taken orally at home.
- Injection: In some cases, chemotherapy drugs may be administered through injections, either intramuscularly (into a muscle) or subcutaneously (under the skin).

- Treatment Cycles: Chemotherapy is usually given in cycles, with each cycle consisting of a treatment period followed by a rest period. The specific schedule and duration of cycles depend on the treatment plan. For example, a cycle may consist of receiving chemotherapy for a few consecutive days, followed by a rest period of several weeks to allow the body to recover before the next cycle begins. This cycle is repeated until the planned number of cycles is completed.
- Monitoring and Follow-up: Throughout the treatment, the healthcare team will closely monitor the patient’s progress. This includes regular check-ups, blood tests, imaging scans, and other assessments to evaluate the response to treatment and manage any potential side effects. The treatment plan may be adjusted based on the individual’s response and any changes in the cancer’s status.
- Supportive Care: Managing the side effects of chemotherapy is an important aspect of treatment. The healthcare team will provide supportive care measures to help alleviate side effects and enhance the patient’s well-being. This may include medications to prevent or minimize nausea and vomiting, supportive medications for managing pain, nutritional support, counseling, and guidance for maintaining a healthy lifestyle during treatment.
- Completion of Treatment: Once the planned cycles of chemotherapy are completed, the healthcare team will evaluate the treatment’s effectiveness. Additional tests, such as imaging scans or biopsies, may be conducted to assess the cancer’s response. Depending on the results, further treatment options, such as surgery or radiation therapy, may be recommended.
- Diagnosis and Treatment Plan: The process begins with the diagnosis of cancer or the condition requiring chemotherapy. After a thorough evaluation, which may include imaging tests, biopsies, blood work, and other diagnostic procedures, an oncologist (cancer specialist) will determine if chemotherapy is a suitable treatment option. They will develop an individualized treatment plan based on the type and stage of cancer, the patient’s overall health, and other factors

Chemotherapy Cost
In general, chemotherapy treatment costs in India can range from INR 50,000 to several lakhs (hundreds of thousands) of Indian Rupees per cycle. The number of cycles required will depend on the individual treatment plan, which can vary based on the cancer type, stage, and the patient’s response to treatment. The total cost of chemotherapy can accumulate significantly over the entire course of treatment.

Additional costs may be incurred for pre-treatment evaluations, diagnostic tests, imaging scans, laboratory tests, consultations with specialists, supportive medications, and supportive care measures to manage side effects. These costs can vary and should be discussed with the healthcare provider for a more accurate estimate.
