The primary aim of chemotherapy is to hinder or stop the growth of speedily dividing cells, particularly those accountable for the progression of cancer. The operation of this mechanism involves the restraint of cellular division and multiplication.   The effectiveness of this treatment method has been proven in the fight against cancer. However, it possesses the inherent capacity to induce harm to non-malignant cells and give rise to undesirable adverse reactions.   When is chemotherapy required?   Metastatic cancer patients, or those at greater risk of metastasis, frequently receive chemotherapy. The medicine's active component can inhibit cancer proliferation or eliminate malignant cells. Patients often undergo chemotherapy before or after surgery to shrink their tumors or eliminate cancer cells.   Chemotherapy’s Mechanisms in Cancer Treatment   Chemotherapy is a way to treat cancer with medicine that goes all around the body. It uses drugs to find and kill the cancer cells. The following explanation outlines the functional mechanisms:  
  • Disrupting Cell Growth: Chemotherapy drugs stop cancer cells from growing like they should. They mess up important cell activities like copying DNA and splitting into new cells. This slows down or stops the cancer cells from spreading.
 
  • DNA Damage: Some chemotherapy drugs harm the DNA inside cancer cells. DNA is like a cell's instruction manual. Cells die when they are incapable of repairing the damage and continue replicating properly. This reduces the likelihood that the cancer may spread.
 
  • Making Cells Self-Destruct: Chemotherapy sets off a process called "apoptosis" in cancer cells. It's like telling the cells to destroy themselves. This aids in the removal of harmful cells.
 
  • Boosting the Immune System: Chemotherapy has additional benefits, including boosting the immune system. To achieve this, dying cancer cells secrete signals that direct the immune system to combat the cancer more effectively.
 
  • Cutting Off Blood Supply: Some chemotherapy drugs stop new blood vessels from forming around tumors. Tumors need these blood vessels to get food and oxygen. They become less effective when they are unable to acquire them.
 
  • Stopping Cancer from Spreading: Chemotherapy can prevent metastasis, the proliferation of cancerous cells. The above approach considerably inhibits cancer development.

Using Many Drugs Together: Sometimes, doctors use more than one chemotherapy drug at the same time. This treatment can improve effectiveness and prevent drug resistance.
