Chemotherapy is a treatment method administered with drugs to destroy cancer cells or control their growth. Medically, it works by preventing cell division, thereby shrinking tumors or stopping their spread. Used in the treatment of various types of cancer, chemotherapy is generally administered through intravenous infusion or oral medications.
What Is Chemotherapy?
Chemotherapy is a drug-based treatment method used in cancer therapy. Also known as “chemo,” this treatment works by destroying cancer cells or stopping their growth and multiplication. Managed by oncologists, chemotherapy may be administered alone or in combination with other treatment methods such as surgery and radiotherapy.
Chemotherapy can be used to eliminate remaining cancer cells after surgery, shrink tumors, completely eliminate the disease, or simply alleviate symptoms. Chemotherapy can be applied both in primary cancers, which have not spread, and in metastatic cancers, which have spread to other parts of the body. The choice of medications and the treatment plan are determined based on the location and stage of the cancer, as well as the patient’s overall health condition.

Why Is Chemotherapy Performed?
Chemotherapy is one of the most commonly used methods in cancer treatment. Chemo is used to treat cancer. This is because cancer cells grow and multiply much faster than healthy cells in the body.
There are many different chemotherapy drugs that can be used in treatment. These medications may be administered alone or in combination with multiple drugs to treat various types of cancer.
Although chemotherapy is an effective treatment option for many types of cancer, it also carries the risk of side effects. In some patients, side effects may be mild and manageable, while in other cases they may lead to more serious health problems.
How Is Chemotherapy Treatment Administered?
Chemotherapy drugs can be administered using different methods. The most commonly preferred method is intravenous chemotherapy. In this method, the medication is delivered through a needle inserted into the arm or through a special vascular access device placed in the chest area.
Some chemotherapy drugs can be taken orally. These medications, available in tablet or capsule form, are used according to the dosage and duration determined by the physician. Chemotherapy may also be administered by injection. In this method, the drug is injected into the muscle or under the skin with a needle, similar to a vaccination. Topical chemotherapy is preferred for certain types of skin cancer. In this method, a cream or gel containing chemotherapy medication is applied directly to the skin.
In some cases, chemotherapy drugs may also be administered regionally. The medication can be delivered directly into the abdominal cavity (intraperitoneal), chest cavity (intrapleural), central nervous system (intrathecal), or bladder (intravesical).
Finally, chemotherapy drugs may also be administered directly to the tumor itself. During surgery, thin disc-shaped drug carriers may be placed in the tumor area to provide controlled drug release. In addition, chemotherapy can also be injected directly into the blood vessel supplying the tumor.
What Are the Benefits of Chemotherapy
Chemotherapy has both advantages and disadvantages. Therefore, before starting treatment, patients should consult with their doctor and manage the process together. Chemotherapy can shrink cancer or slow its growth.
This may help prolong life expectancy and relieve symptoms. In some patients, tumor shrinkage may make surgical intervention possible.
Chemotherapy administered after surgery may reduce the risk of cancer recurrence. In addition, more frequent monitoring, testing, and physician follow-up during treatment may provide reassurance to patients. The advantages of chemotherapy are listed below:
- Shrinking cancer or slowing its growth
- Prolonging life expectancy and relieving symptoms
- The possibility of making surgery feasible
- Reducing the risk of recurrence
- Providing regular monitoring and follow-up opportunities
What Are the Side Effects of Chemotherapy?
Chemotherapy is an effective treatment method for many types of cancer. However, like other cancer treatments, it may cause certain side effects. Being informed about these side effects makes it easier to closely monitor the process and communicate with your healthcare team about preventive or symptom-relieving measures.
The side effects of chemotherapy may vary from person to person. This depends on the type and location of the cancer, the type and dosage of the chemotherapy drugs used, as well as the patient’s overall health condition.
Chemotherapy-related side effects may differ according to the type of medication and the dosage administered. The most common side effects of chemotherapy include fatigue, hair loss, low platelet count, a decrease in white blood cells, and an increased risk of infection associated with this condition.
Additionally, anemia, nausea, vomiting, appetite changes, constipation, diarrhea, and mouth sores are also common conditions. The side effects of chemotherapy are listed below:
- Fatique
- Hair loss
- Thrombocytopenia (low platelet count)
- Neutropenia (low white blood cell count)
- Increased risk of infection
- Anemia (low red blood cell count)
- Nausea and vomiting
- Changes in appetite
- Constipation
- Diarrhea
- Mouth sores
- Peripheral neuropathy or other nerve-related problems
- Skin and nail changes
- Loss of bowel or bladder control
- Weight changes
- Anxiety
- Depression
- Changes in libido and sexual function
- Fertility problems
Who Is Chemotherapy Given To?
Chemotherapy is one of the main treatment methods used to destroy cancer cells in cancer patients. In some types of cancer, it may be used as a standalone treatment option, while in other cases it is preferred after treatments such as surgery to eliminate hidden cancer cells that may remain in the body.
This approach is called adjuvant therapy. In some patients, chemotherapy is administered as neoadjuvant therapy to shrink the tumor and facilitate further treatments such as surgery or radiotherapy.
In advanced-stage cancers, chemotherapy may also be used as palliative treatment, not to completely eliminate the disease, but to relieve symptoms and improve quality of life.
What Are the Types of Chemotherapy?
Chemotherapy is one of the most commonly used methods in cancer treatment and may be administered in different ways depending on the stage of the disease, the extent of its spread, and the treatment goals.
In some cases, it is preferred to shrink the tumor before surgery; in others, it is used after surgery to reduce the risk of recurrence, or to preserve the patient’s quality of life. The types of chemotherapy are listed below:
- Neoadjuvant Chemotherapy
- Adjuvant Chemotherapy
- Palliative Chemotherapy
Neoadjuvant Chemotherapy
Neoadjuvant chemotherapy is a treatment method administered before surgery or radiotherapy. Its goal is to reduce the size of the tumor, making it possible to remove less tissue during surgery. It also increases the likelihood of organ-preserving surgery and facilitates subsequent treatment processes.
Adjuvant Chemotherapy
Adjuvant chemotherapy is a treatment method applied after surgical intervention. It aims to eliminate microscopic cancer cells that may remain even after the tumor appears to have been completely removed. In this way, the risk of cancer recurrence is reduced and long-term treatment success is improved.
Palliative Chemotherapy
Palliative chemotherapy is used in advanced stages of cancer when complete elimination of the disease is not possible. Its main purpose is to control the disease, relieve symptoms, and improve quality of life. By slowing tumor growth, it helps reduce pain and other complaints, making the patient’s treatment process more comfortable.
How Long Does Chemotherapy Take?
The duration of chemotherapy varies depending on the treatment administered; it may last as little as 30 minutes or up to 8 hours in some cases. Throughout the treatment, the nurse regularly monitors vital signs and ensures that no adverse reactions to the medications occur. During this process, the patient may rest, eat, or engage in different activities to pass the time. If the patient wishes to move around, the IV pole can be carried along with them. Once the session is completed, the intravenous line is flushed with serum, and the port or needle is removed. Afterward, patients may generally be asked to wait an additional 30 minutes to observe for possible drug reactions. Following this stage, the patient may return home.
