Chemotherapy is popularly used in prostate cancer treatment to kill malignant cells and reduce the risk of relapse. It mainly consists of five phases: pre-surgery, induction, consolidation, continuation (maintenance), and adjuvant.
Another important purpose of chemotherapy is to restore the immune system by increasing the number of white blood cells. The therapeutic effect will be better if the immune revitalization and killing of tumour cells can be achieved at the same time.
During chemotherapy, the body is likely to experience some side effects such as fatigue and nausea. The chemotherapy may result in baldness, hair loss, or hair regrowth which may be permanent or temporary. Chemotherapy can also lead to kidney dysfunction and blood disorders such as thrombocytopenia and aplastic anaemia.
For example, chemo-resistant ovarian cancer has an extremely poor prognosis. Some chemotherapy drugs may induce the development of drug resistance in tumours. Chemotherapy can also cause secondary cancers in some cancer patients.
Some long-term hospitalization is required for patients with certain types of cancer after chemotherapy. Because chemo-sensitive tumours shrink, the remaining tumour cells may become more aggressive.
Chemotherapy has been used for many years for prostate cancer treatment in Gurgaon. However, there are still many problems when it is applied to cancer patients. In particular, r the side effects that occur during chemotherapy for different types of cancers and even for the same type of cancer in different patients.
For example, chemo-resistant ovarian cancer has an extremely poor prognosis. Some chemotherapy drugs may induce the development of drug resistance in tumours. Chemotherapy can also cause secondary cancers in some cancer patients. So, it is essential to get treated by the best cancer specialist in Gurgaon
Some long-term hospitalization is required for patients with certain types of cancer after chemotherapy. Because chemo-sensitive tumours shrink, the remaining tumour cells may become more aggressive and resistant to chemotherapy or other treatments.
The Process of Treatment
Chemotherapy involves the use of toxic chemicals to reach the tumour cells. Chemotherapy can be administered intravenously, injected through the skin, inhaled, or into the stomach. More than 4500 different drugs and combinations of drugs are used in chemotherapy. The chemotherapy that is given by the cancer specialist in Gurgaon depends on the type and stage of the cancer.
- The Preoperative
The preoperative phase is before surgery to improve body function by removing blood clots. This improves circulation through the administration of anti-clotting medication such as Heparin or Warfarin.
- The Induction Phase
The induction phase is a period of treatment in which cancer cells are targeted and killed by inducing tumour cell death (apoptosis). The induction phase can be divided into two phases-Unmanaged chemo-radiated diarrhoea and adjuvant chemotherapy.
- Chemotherapy
Chemotherapy is a very toxic treatment. So, it should not be used together with blood transfusion or surgery. This is because both may cause side effects chemotherapy should not be used for people who have an allergy to chemo drugs. It is not advisable for people who are unwilling to accept the side effects of this treatment.
The use of chemotherapy can only eliminate about 20-30% of cancer cells. However, these cells may be resistant to other treatments. This means that chemo drugs have very poor efficacy with some cancers because the cancer cells cannot be killed effectively. The time interval between chemotherapy is usually 4 weeks.
- Anaphylaxis
When cancer drugs are injected into the body, some of them can cause severe allergic reactions or even death. This is called “anaphylaxis”. Anaphylaxis occurs when the immune system responds to a foreign substance in the body.
This is normally a harmless protein found in a particular food. The immune system mistakenly treats this harmless protein as a foreign substance and attacks it. This is called an allergic reaction. Anaphylaxis can be life-threatening and must be treated immediately if it is to be controlled.
As with induction, several drugs are frequently combined for this purpose to reduce the risk that cancer may develop resistance. A common strategy involves administering a drug on a specific schedule for many months (or even years). This is known as a chronic regimen or maintenance therapy.
Chemotherapy is sometimes used after surgery to kill any remaining cancer cells that were not removed by the surgery. This is known as adjuvant chemotherapy, and it is administered for several months after surgery.
- Adjuvant Chemotherapy
Adjuvant chemotherapy uses drugs with different mechanisms of action to kill cancer cells in the human body. Chemotherapy may also be used together with radiation therapy in some cancers to increase the effectiveness of both treatments. The purpose of adjuvant chemotherapy is mainly to reduce the risk that cancer will come back (recur).
Chemotherapy may also be used to treat cancer that has spread to other parts of the body. This type of chemotherapy is called “adjuvant”. Chemotherapy may also be used for patients with a certain type of cancer to see how well it works or if it can be combined with other treatments. This is called “palliative” treatment and is used to make cancer patients feel better or have more time without their disease getting worse.
Adjuvant chemotherapy uses drugs with different mechanisms of action to kill cancer cells in the human body. Chemotherapy may also be used together with radiation therapy in some cancers to increase the effectiveness of both treatments.
In some cases, chemotherapy treatments are used to treat advanced cancer, before death. This is called “end of life” or “palliative chemotherapy”, and is typically used for patients who do not have much time left to live.
Chemotherapy may also be used for people whose disease has been slow growing and is now at an advanced stage before death. This type of chemotherapy is called “acute leukaemia” or “acute lymphocytic leukaemia”.
Conclusion
As the body is poisoned by chemotherapy and other treatments, the immune system becomes weakened. The body loses the ability to fight pathogens that are normally present in the body. The common signs of this are fatigue, fever, and pain.
In addition, cancer can develop in other places in the body such as the heart or bones (lymphoma). This is known as “chemotherapy-induced thrombocytopenia” or CIT. It is possible to have a blood clot during chemotherapy that can be fatal but this is not common. When chemotherapy is used with radiotherapy, it can cause side effects.
