Chemotherapy: Definition, Administration Methods, and Duration
In some cases, chemotherapy alone may not be effective, and radiotherapy or surgical intervention may be necessary alongside it.
Chemotherapy
Chemotherapy is performed to destroy cancer cells growing in the bodies of individuals who have cancer through drug treatment. These drugs are generally referred to as anticancer drugs. The drugs and methods used vary depending on the type and stage of cancer.
- The most important purpose of chemotherapy is to eliminate cancer, regardless of its type and stage.
- In accordance with this purpose, cancer cells spreading throughout the body are attempted to be controlled. The growth and spread of cancer is prevented and controlled through chemotherapy treatment.
- It is also aimed at preventing health problems that arise during the cancer process. The pain that occurs is attempted to be minimized through this method.
In some cases, chemotherapy alone may not be effective, and radiotherapy or surgical intervention may be necessary alongside it.
What is Chemotherapy?

It means treating cancer diseases with medication. Depending on the type and stage of cancer, there may be changes in the medications and duration of use. With medication, cancer cells are targeted with the aim of destroying these malignant cells.
Non-cancerous healthy cells have the potential to regenerate even if they are damaged. A damaged cancer cell cannot regenerate itself. However, the spread of cancer cells throughout the body progresses very rapidly. For this reason, it must be treated and controlled.
How is Chemotherapy Administered?
The chemotherapy process can be explained in two ways. First, preparing the patient for chemotherapy treatment, and second, administering the chemotherapy treatment.
Preparing the Patient for Chemotherapy Treatment:
- Drugs given in cancer diseases are generally administered to the patient through an intravenous line. If the patient does not want an intravenous line to be placed each time, a tube called a catheter or a device called a port is placed on one of the veins in the neck.
- Before chemotherapy treatment is started, liver function tests, kidney function tests, and complete blood count tests are performed on the patient. A cardiac examination should also be performed.
- Chemotherapy treatment affects the body's ability to fight infections. For this reason, if the patient has dental infections, they should have a dental examination before treatment.
- Since chemotherapy will also affect the patient's eggs and sperm, doctors should provide this information beforehand. An informed patient may request to freeze their eggs or sperm if desired. The patient should also be told to prepare themselves for another side effect, hair loss.
- Finally, the preparation phase is completed by discussing how the patient will return to their routine life.
Afterward, chemotherapy treatment is administered to the patient.
Administering Chemotherapy to the Patient:
- Chemotherapy drugs are administered to the patient through a method called infusion. That is, drugs placed in serum are given to the patient through an intravenous line.
- Chemotherapy drugs can also be given to the patient orally in the form of capsules or tablets.
- Chemotherapy drugs are also administered to the patient as a needle placed under the skin.
- Chemotherapy drugs are given directly to cancer cells present in the patient.
- If there are blood vessels that feed the tumor and cancer, drugs can also be applied to these vessels.
How Long Does Chemotherapy Last?

Like any disease, the process in this disease is personalized and varies from patient to patient. Many factors such as the patient themselves, the type of cancer, and the stage of cancer can change this duration.
However, in general, while the administration time of some cancer drugs is about 1-2 minutes, the administration of others varies between 2-5 days. Based on the doctor's decision according to the cancer type, either a single drug or 2-4 drugs can be used together.
The administration of drugs and the patient's rest period is referred to as one cycle. These cycles are at least 4 sessions but can extend up to 1-2 years. The drugs can be administered on consecutive days, once a week, once every 15 days, or once every 21-28 days.
How Long Does a Cancer Patient Receiving Chemotherapy Survive?
The chemotherapy process and dose varies depending on the patient and cancer type. While the survival rate of patients was very low in the past, with current technology, the survival rate of patients has increased considerably.
Not all cancer is actually fatal. While advanced-stage cancers can be life-threatening, drug treatment can extend this period to 1-2 years. However, in some cases, cancer patients have been observed to live for more than 5 years.
It is not appropriate to predict a lifespan for an individual who is a cancer patient. At this stage, doctors provide the most accurate information. By consulting with qualified professionals and undergoing an examination as soon as possible, you can find quick and accurate answers to all your questions.
How Long Does One Cycle of Chemotherapy Last?
Chemotherapy is the term given to the treatment of cancer cells with medication. The dose and duration of these procedures varies from person to person and depends on the disease.
One cycle of chemotherapy proceeds as follows. For example, a patient receives chemotherapy treatment for one week. The doctor gives a 3-week recovery period for healthy cells that are damaged along with cancer cells to recover. This 4-week period is referred to as one cycle.
How Do Blood Values Increase After Chemotherapy?
While undergoing chemotherapy, a decrease can be seen in platelets and red and white blood cells. The reason for this is the heavy drugs used. This is normal, and after treatment, it is necessary to stay in contact with your doctor to increase these values again.
Since the body has received intense medication, patients who do not want to proceed with medication adjustment should eat foods rich in iron. These include:
- Red meats,
- Chicken and turkey meat,
- Fish meats such as tuna and salmon,
- Eggs,
- Tofu and soybeans,
- Dried beans, lentils, chickpeas, fava beans, cranberry beans and other legumes rich in protein and iron,
- Hazelnuts, walnuts, and almonds,
- Fresh vegetables and fruits,
- Green leafy vegetables such as mint, parsley, arugula, and spinach,
- Tahini and molasses,
- Dried fruits should be consumed under doctor supervision.
Why is Chemotherapy Given Every 21 Days?
Chemotherapy is an important component of cancer treatment and is used in patients to destroy cancer cells or stop their growth. The process of giving chemotherapy every 21 days is determined to minimize the multiplication cycle of cancer cells and damage to healthy cells.
Chemotherapy drugs attack rapidly dividing cells to kill cancer cells or slow their growth. However, they can also damage healthy cells in the body. For this reason, a recovery period is given between chemotherapy sessions. The 21-day period is preferred to coincide with the time when cancer cells are most sensitive and at the same time to increase the body's chance of recovery.
Every patient is different, and chemotherapy protocols are personalized. In some cases, chemotherapy may be administered at different intervals or timeframes. Doctors determine the most appropriate treatment plan by considering the patient's cancer type, stage, overall health status, and side effects.
In conclusion, administering chemotherapy sessions every 21 days is not a standard set to affect cancer cells and optimize the body's chance of recovery, but it is commonly used in many cancer treatment protocols. It is important that patients collaborate with their doctors to determine the most appropriate treatment plan.
Pain After Chemotherapy
Chemotherapy is commonly used in cancer treatment, but it can cause some side effects during and after treatment. Pain after chemotherapy is one of these side effects. Pain after chemotherapy can occur due to various reasons.
First, chemotherapy drugs target cancer cells but can also damage healthy cells in the body. Therefore, pain after chemotherapy may result from tissue damage or inflammation in the body. Additionally, some chemotherapy drugs can affect bone marrow, which can lead to bone pain.
To manage pain after chemotherapy, doctors may suggest different treatment methods depending on the cause of the pain. Painkillers, anti-inflammatory drugs, physical therapy, or other treatment options can be used. Treatment is personalized based on the intensity and duration of pain and the patient's overall health status.
Pain after chemotherapy can negatively affect the patient's quality of life, so it is important to communicate openly about pain and follow doctor's advice. Pain experienced during treatment should be monitored by doctors and appropriate treatments should be applied when necessary. This can help patients have a more comfortable experience during chemotherapy treatment.

When Do Hair, Eyebrows, and Eyelashes Grow Back After Chemotherapy?
Hair, eyelashes, and eyebrows of patients undergoing chemotherapy treatment may fall out after treatment. This shedding is not permanent, and cells under the skin renew themselves and hair formation begins again. While some chemotherapy treatments do not cause shedding, some can. It should be remembered that this situation will not be permanent.
However, one should be prepared for hair loss. This shedding begins within 14 days following treatment and increases and multiplies over the following 1-2 months.
Since hair will not start growing immediately after shedding, the patient needs to be prepared for this situation. They need to give their body time to renew its cells and slowly eliminate chemotherapy drugs.

Hair usually begins to grow back to replace hair loss within a few weeks to a few months after chemotherapy ends. However, this process can vary based on personal factors.
When new hair grows, this hair usually differs in color or texture from the original hair. However, over time, hair can return to normal. When hair starts to regrow, it is important to follow a gentle hair care routine.
In conclusion, the process of hair regrowing after chemotherapy can vary from person to person and may differ depending on the type of treatment. However, hair usually begins to regrow within a few weeks to a few months after treatment ends, which is a hopeful development for patients.
