TARGETED THERAPY

How do targeted therapies for cancer work? 


Most types of targeted therapies help treat cancer by blocking specific proteins that help tumors grow and spread throughout the body. This differs from chemotherapy, which often kills rapidly growing and dividing cells. Below we discuss different possibilities for targeted therapy in the treatment of cancer.



Helps the immune system destroy cancer cells.


 One reason cancer cells proliferate is because they can hide from the immune system. Certain targeted therapies can mark cancer cells so that the immune system can find and destroy them more easily. Other targeted therapies help strengthen the immune system and fight cancer better.


Stops signals that help form blood vessels.


 For a tumor to grow beyond a certain size, it must form new blood vessels in a process called angiogenesis. Tumors send signals to initiate angiogenesis. Some targeted therapies, called angiogenesis inhibitors, interfere with these signals to prevent the blood supply from forming. Without a blood supply, the tumor remains small. Alternatively, if the tumor is already supplied with blood, these treatments may kill blood vessels and shrink the tumor. Learn more about angiogenesis inhibitors.


Delivers cytotoxic substances to cancer cells.


 Some monoclonal antibodies are combined with cell-killing agents such as toxins, chemotherapy drugs, and radiation. When these monoclonal antibodies bind to targets on the surface of cancer cells, the cells take up cytotoxic agents and kill the cells. Non-targeted cells are not damaged.


Causes cancer cell death.


 Healthy cells die in an orderly fashion when damaged or no longer needed. However, cancer cells have a way of circumventing this deadly process. Some targeted therapies can cause cancer cells to undergo a process of cell death called apoptosis. It starves the cancer with the hormones it needs to grow. Some breast and prostate cancers require specific hormones to grow. Hormone therapy is a type of targeted therapy that works in two ways. Some hormone therapies stop the body from making certain hormones. Some prevent hormones from affecting

Arrhythmia surgery

  Arrhythmia surgery is a medical procedure performed to treat irregular heartbeats, also known as arrhythmias. These abnormal heart rhythms can cause symptoms such as fatigue, dizziness, shortness of breath, and even chest pain. If left untreated, they can lead to serious complications, such as stroke or heart failure. Arrhythmia surgery is usually recommended when medication and other non-invasive treatments fail to control the irregular heartbeats. The procedure involves the use of various techniques to destroy or modify the abnormal electrical pathways in the heart. Some of the techniques used in arrhythmia surgery include catheter ablation, maze procedure, and implantable devices such as pacemakers and defibrillators. Catheter ablation is a minimally invasive procedure in which a thin, flexible tube (catheter) is inserted through a vein in the groin and threaded up to the heart. Once in the heart, the catheter is used to deliver energy (such as radiofrequency or cryotherapy)...

CANCER AND MENTAL HEALTH- IT DOESN’T JUST AFFECT YOUR BODY

As far as treatment for cancer goes, with recent technology and advanced methods of treating the disease the procedure has of course become a lot less painful and efficient, decreasing mortality rate by quite a lot as compared to traditional methods of treatment. Doctors now have a better understanding of the causes, symptoms and effects and how to treat their patients accurately. The patients too are always updated and consoled to the best one can, but does it mean that those affected are free of mental and emotional distress? Unfortunately the answer is still a no for this one. Knowing that one has ‘cancer’, irrespective of the sort and the intensity, the word itself has the capability to put a person into deep distress. Feelings of depression, anxiety and fear are very common in such cases. It is a tug of war between life and death and the exhaustion of anticipation is clearly high on a person and their loved ones. No matter how much knowledge and sympathy or compassion one might ge...

Blood Cancer- Part 2

  How is blood cancer diagnosed? A physical examination to check your overall health is often the first step in making a diagnosis. Your doctor will look at your body and lymph nodes, look for signs of infection, and review your medical history. The diagnosis of blood cancer can be made with a variety of tests and procedures. The type of blood cancer that is suspected will dictate what you need. In order to make a diagnosis, your care team may suggest testing and evaluate all of the results with you. Biopsies A biopsy is a procedure that takes cell samples for a pathologist to look at in a lab. A lymph node biopsy, which involves taking a sample of lymph tissue or the entire lymph node, may be required for certain types of blood cancer, such as lymphoma. Certain types of blood cancer can be identified by testing your bone marrow, the place where blood cells are made. A bone marrow aspiration is a method by which a small amount of blood, bone, and bone are taken from either a breast...
