What is Chemotherapy?
Chemotherapy, also known as cancer treatment chemotherapy, is a systemic medical treatment that uses chemotherapy drugs to target and destroy rapidly dividing cells, including cancer cells. It can be used as a primary treatment to shrink or eliminate tumors, as an adjuvant therapy following surgery or radiation, or to manage advanced cancer by slowing its growth and relieving symptoms.
The chemotherapy procedure involves administering drugs orally, intravenously, or via injection, typically in cycles, allowing the body to recover between sessions. The chemotherapy process is carefully monitored by oncologists and healthcare professionals to maximize effectiveness while minimizing side effects. Patients often experience temporary effects on healthy rapidly dividing cells, which is why after chemotherapy care is an essential part of treatment.
What are the types of chemotherapy?
There are several chemotherapy types, each using specific chemotherapy drugs to target cancer cells differently. The choice of therapy depends on the type of cancer, its stage, location, and the patient's overall health. Common types include:
- Alkylating Agents: These drugs damage the DNA of cancer cells to stop their growth. Example: Cyclophosphamide. Commonly used for leukemia and lymphoma. Side effects may include secondary cancers.
- Antimetabolites: These interfere with DNA and RNA synthesis, preventing cancer cells from dividing. Example: Methotrexate. Used for leukemia, breast, and ovarian cancers. Side effects include bone marrow suppression.
- Plant Alkaloids: These stop cell division by disrupting microtubules in cancer cells. Examples: Vincristine, Paclitaxel. Used for breast, lung, and lymphoma. Side effects may include neuropathy.
- Antitumor Antibiotics: These disrupt DNA and RNA in cancer cells. Example: Doxorubicin. Used for leukemia and breast cancer. Side effects can include heart and lung toxicity.
- Topoisomerase Inhibitors: These block DNA repair, preventing cancer cells from reproducing. Example: Irinotecan. Used for colorectal and lung cancers. Side effects include diarrhea and low blood cell counts.
- Platinum Compounds: These drugs damage DNA to stop cancer cell growth. Example: Cisplatin. Used for testicular and ovarian cancers. Side effects may include kidney damage.
Understanding the types of chemotherapy helps patients and caregivers anticipate treatment schedules, potential chemotherapy side effects, and plan for after chemotherapy care.

Who needs chemotherapy treatment?
Chemotherapy treatment is recommended for patients diagnosed with cancer or certain blood disorders. Individuals whose tumors cannot be surgically removed, or whose cancer has spread (metastatic cancer), may benefit from cancer chemotherapy. It is also considered for patients needing palliative care to relieve symptoms and improve quality of life.
What conditions does chemotherapy treat?
Chemotherapy indications include a variety of medical conditions, primarily cancer:
- Solid tumors: Breast, lung, colorectal, ovarian, and other cancers.
- Blood cancers and hematologic diseases: Leukemia, lymphoma, and multiple myeloma.
- Advanced or metastatic cancers: To slow disease progression and control symptoms.
It can also be used for neoadjuvant therapy to shrink tumors before surgery or radiation and for adjuvant therapy to eliminate residual cancer cells after treatment.
When would a doctor recommend chemotherapy?
Doctors may recommend chemotherapy treatment in situations such as:
- When surgery or radiation alone is insufficient.
- To reduce the risk of cancer recurrence after primary treatment.
- To make tumors more operable through neoadjuvant chemotherapy.
- To manage advanced cancer and control symptoms in palliative care settings.
Why is chemotherapy done?
The primary purpose of cancer chemotherapy is to destroy cancer cells or stop their growth. It is done to:
- Treat primary cancer when other options are limited.
- Reduce tumor size before surgery or radiation.
- Prevent recurrence after surgery.
- Control cancer spread and improve quality of life.
- Manage blood-related cancers like leukemia and lymphoma.
How should I prepare before the chemotherapy procedure?
Preparing for chemotherapy treatment involves both physical and emotional readiness to ensure the best results. Patients should:
- Understand the treatment: Discuss the chemotherapy procedure, including its purpose, duration, and potential chemotherapy side effects, with your oncologist.
- Plan transportation: Arrange rides to and from appointments, as fatigue is common after sessions.
- Nutrition and hydration: Maintain a balanced diet and stay well-hydrated. A dietitian can provide tailored guidance.
- Emotional support: Seek help from family, friends, or support groups to manage anxiety.
- Rest and exercise: Light exercise and adequate rest improve stamina and overall health.
- Dress comfortably: Wear loose-fitting clothes for easier access during cancer chemotherapy sessions.
- Organize personal items: Bring reading materials, music, or entertainment for the duration of treatment.
- Be informed: Learn about what happens in chemotherapy and strategies to manage side effects.
What tests are done before chemotherapy?
Before starting cancer chemotherapy, several tests are performed to ensure safety and effectiveness:
- Blood tests: Assess overall health, blood cell counts, and organ function.
- Imaging scans: Evaluate tumor size and spread.
- Medical review: Your oncologist will review all medications, supplements, and existing health conditions.
These steps are part of the chemotherapy process and help your healthcare team tailor the chemotherapy treatment to your needs.
Should I stop eating, drinking, or taking medicines before chemotherapy?
Your doctor will provide specific instructions based on your chemotherapy procedure:
- Fasting: Some chemotherapy drugs may require you to avoid eating or drinking for a few hours before the session.
- Medications: Inform your doctor about all supplements, vitamins, and prescriptions. Certain medications may need to be paused to reduce side effects or interactions with chemotherapy drugs.
- Hydration: Drinking water is usually encouraged unless your oncologist advises otherwise.
Following these instructions ensures the chemotherapy process is as safe and effective as possible.
Steps Involved in Chemotherapy Procedure
Chemotherapy is a treatment approach commonly used to treat cancer. It involves by using medications to target and destroy cancer cells or slow their growth. The specific steps involved in a chemotherapy procedure can vary depending based on the type of cancer, the chemotherapy drugs being used, and the patient's individual needs.
However, here are the general steps involved in a chemotherapy procedure:
- Medical Assessment and Consultation: Before chemotherapy begins, the patient undergoes a comprehensive medical evaluation, which includes physical examinations, blood tests, imaging scans, and occasionally a biopsy. This helps determine the type, stage, and spread of the cancer.
- Treatment Planning: Oncologists create a personalized treatment plan based on the assessment. It includes the chemotherapy drugs, dosage, schedule, and treatment duration, taking into account the patient's health and the specifics of their cancer.
- Access Placement: If necessary, a central venous catheter (such as a port or catheter) is surgically inserted to facilitate the administration of chemotherapy and blood draws, making the process easier and more comfortable.
- Preparation for Treatment: On the treatment day, the patient may be asked to provide a blood sample for additional tests. The medical team checks if the patient is ready for chemotherapy that day.
- Administration of Chemotherapy: Chemotherapy can be given through various methods, including IV infusion, oral pills, injections, or topical applications. IV treatments can take several hours, and patients are monitored by medical staff throughout the procedure.
- Monitoring and Support: During chemotherapy, the medical team closely monitors the patient's vital signs and manages any side effects that may arise. Patients may also receive fluids, medications for side effects, and other supportive care.
- Completion of Treatment Session: Once the chemotherapy drugs are fully given, the patient is observed for any immediate reactions before being allowed to leave.
- Recovery and Follow-Up: After chemotherapy, the patient can often go home or may need to stay overnight, depending on the treatment. They receive instructions on managing side effects, staying hydrated, and following a healthy lifestyle.
- Subsequent Treatment Sessions: Chemotherapy usually follows a cycle of treatment sessions and rest periods, allowing the body time to recover. The number and frequency of sessions depend on the individual treatment plan.
- Ongoing Monitoring and Adjustments: Throughout chemotherapy, the patient's progress is tracked with regular check-ups, blood tests, and scans. The treatment plan may be adjusted based on how the patient is responding and any changes in their health.
What type of anesthesia is used for chemotherapy?
Most chemotherapy procedures do not require general anesthesia. For IV infusions, patients are usually awake. Sedation may be provided in rare cases if needed for comfort, but chemotherapy drugs are administered safely without full anesthesia.
How long does a chemotherapy treatment session typically last?
The duration of a chemotherapy procedure depends on the type of drugs and method of administration:
