What is Chemotherapy?
Cancer chemotherapy is one of the most common and effective treatment methods used for different types of cancer. Chemotherapy helps manage cancer symptoms by using drugs that either kill the cancer cells or prevent them from progressing further.
Artemis Hospitals offer advanced chemotherapy treatment options with modern techniques and drugs to prevent the cancer symptoms from getting worse. Oncologists rely on chemotherapy for treating breast cancer, blood cancer, or even stomach cancer, with high remission rates.
How Does Chemotherapy Work in Cancer Treatment?
Chemotherapy works by targeting fast-growing cells in the body, which includes cancer cells. Since cancer cells grow and divide rapidly, chemotherapy drugs are effective in halting their progression. However, because chemotherapy affects all rapidly dividing cells, it can also impact healthy cells, which leads to some of the common side effects.
Who Needs Chemotherapy?
Chemotherapy is required for patients diagnosed with various types of cancer. However, depending on the cancer type and stage, chemotherapy may be used as a primary treatment or in combination with surgery, radiation, or targeted therapies. Oncologists usually recommend:
Chemotherapy for breast cancer
Chemotherapy for blood cancer
Chemotherapy for brain cancer
Chemotherapy for stomach cancer
Chemotherapy for ovarian cancer
Chemotherapy for mouth cancer and oral cancer
What Are The Different Types of Chemotherapies?
Systemic Chemotherapy (Oral, Intravenous, Injections)
This involves chemotherapy drugs that are introduced into the bloodstream, allowing them to reach cancer cells throughout the body. Systemic chemotherapy can be administered in three primary forms:
Oral Chemotherapy
Taken in pill form, oral chemotherapy drugs are absorbed into the bloodstream after ingestion.
Intravenous (IV) Chemotherapy
Delivered directly into the bloodstream through a needle, or catheter into a vein
Injections Chemotherapy
Injected directly into muscles or under the skin.
Regional Chemotherapy (Targeted to Specific Areas)
In this type of chemotherapy, drugs are directly applied to a specific part of the body where the cancer is located. Examples include intrathecal chemotherapy for brain cancers and intra-arterial chemotherapy for liver cancer.
Combination Chemotherapy (Using Multiple Drugs)
Combination chemotherapy uses two or more drugs with different mechanisms of action to target cancer cells more effectively. Chemotherapy is often used in combination with other drugs to attack cancer cells in various ways.

Different Types of Chemotherapy Drugs
Chemotherapy drugs are classified based on their action. Some common drugs include:
These drugs work by altering the DNA of cancer cells, preventing them from reproducing.
These drugs mimic natural substances in the body and interfere with DNA and RNA production.
These are not like typical antibiotics; they prevent cancer cells from reproducing.
These drugs block enzymes that help DNA unwind, which is crucial for cell division.
These interfere with cell division, especially during the phase when cells are dividing.
Used to help reduce inflammation and control certain side effects of chemotherapy.
How Is Chemotherapy Used?
Chemotherapy is a widely used treatment that involves powerful drugs to target and affect rapidly dividing cells in the body. It can be administered in different ways, including orally, intravenously, or through injections, depending on the specific treatment plan. The approach may involve a single drug or a combination of multiple drugs, given in cycles to maximize effectiveness while allowing the body time to recover. The dosage, duration, and method of administration vary based on individual factors such as overall health, the type of condition being treated, and response to therapy. Chemotherapy can be used for several purposes:
Chemotherapy is given before surgery to shrink tumors.
Chemotherapy is given after surgery to kill any remaining cancer cells.
Used to alleviate symptoms and improve the quality of life when cancer is not curable.
In some cases, chemotherapy is used to prevent cancer recurrence.
How to Prepare for Chemotherapy?
Before starting chemotherapy, patients undergo tests to assess their overall health, liver and kidney function, and blood counts. A treatment plan is created based on the type and stage of cancer. Discussing concerns and potential side effects with the oncologist is crucial.
Preparing for chemotherapy Includes:
Pre-treatment counseling to assess side effects, treatment schedule, and diet.
Financial planning to prepare yourself financially.
What Happens During Chemotherapy Treatment?
Chemotherapy sessions vary depending on the type of treatment. The treatment can last anywhere from 30 minutes to several hours, depending on whether it’s an intravenous drip or oral chemotherapy. After each cycle, you’ll likely have a break period before the next treatment begins.
What to Expect After Chemotherapy?
After chemotherapy, patients may experience immediate and delayed side effects. Some people recover quickly, while others may take time to regain their strength. Keep in touch with the oncologist to monitor progress and manage side effects.
What Are the Benefits of Chemotherapy?
Chemotherapy is a widely used treatment for cancer that involves the use of powerful drugs to target and destroy cancer cells. It plays a crucial role in managing various types of cancer, either on its own or in combination with other treatments like surgery or radiation therapy.
