Is chemotherapy safe? What are the long-term side effects?

Image
Chemotherapy is a common and effective treatment used against cancer. It works by destroying fast-growing cancer cells and preventing them from spreading. Many patients worry whether chemotherapy is truly safe and how it affects the body in the long run. A Chemotherapy Cancer Treatment Doctor Delhi usually explains that chemo is given in a scientific, controlled manner and is one of the most proven ways to fight cancer. Is Chemotherapy Safe? Chemotherapy is considered safe under expert supervision. Oncologists decide the drug type, dose, number of cycles, and supportive medicines after checking the patient’s age, cancer stage, organ function, and overall health. Blood tests, liver and kidney tests, and physical examinations are done throughout the treatment to ensure safety. If any unusual effect is seen, the dose can be reduced or paused. So while chemotherapy is strong, it is still a scientifically controlled and medically monitored treatment. Why Do Side Effects Happen? Chemotherap...

Does urethral cancer always require removal of the urethra?

Image
  Urethral cancer does not always require complete removal of the urethra. Many people assume that because the urethra is a narrow tube, cancer automatically leads to major surgery, but that is not true in every case. According to experts and experienced urethral cancer doctor Delhi specialists, treatment depends on the tumor’s size, location, depth of spread, grade of cancer, and the patient’s overall health. When detected early, many tumors can be removed or treated without sacrificing the entire urethra. Organ-preserving options such as endoscopic removal, laser therapy, radiation, or partial surgery are often enough. Complete removal of the urethra—called urethrectomy—is considered only when the cancer is advanced, aggressive, or has spread to surrounding tissues. With modern technology, especially robotic surgery, doctors are able to remove tumors precisely while protecting nearby structures and maintaining urinary function. When full removal is NOT needed Early or surface-le...

Can hormone therapy shrink tumors or only control them?

Image
  How hormone therapy helps shrink tumors Hormone therapy can both shrink tumors and control their growth, but the result depends on the type of cancer and how the patient responds. Some cancers grow because they receive “fuel” from hormones like estrogen, progesterone, or testosterone. When doctors block these hormones or reduce their levels, cancer cells become weak and may stop multiplying. In many breast and prostate cancer patients, tumors shrink noticeably once hormone therapy begins. For example, medicines such as Tamoxifen, Aromatase inhibitors, or drugs that lower testosterone stop the cancer cells from getting the hormones they need. As a result, tumors reduce in size, pain decreases, and treatment such as surgery or radiation becomes easier and more effective. How hormone therapy controls cancer even without shrinking Shrinking is not the only purpose. In many cases, hormone therapy is used to control cancer, especially when it has spread or surgery is not possible. Inst...

Can testicular cancer come back after treatment?

Image
  Testicular cancer can return after treatment, but the overall chances of cure remain very high, even in cases of recurrence. Most patients do extremely well after surgery, chemotherapy, or radiation, especially when guided by an experienced testicular cancer doctor Delhi . However, a small number of patients may develop cancer again months or years later. This can happen because a few microscopic cancer cells sometimes remain hidden in the body and start growing later. That’s why regular follow-up is a key part of testicular cancer care. Common Reasons Why Testicular Cancer Can Come Back Microscopic cancer cells may remain even after treatment. The cancer was at an advanced stage during the first diagnosis. Certain types, especially non-seminomas, may behave more aggressively. The patient missed follow-up scans or tumor marker tests. Some patients have risk factors like larger tumors or lymph node involvement. Signs and Tests That Help Detect Recurrence Early Persistent pain in ...

How does the immune system recognize and destroy cancer cells through immunotherapy?

Image
The immune system is our body’s natural defense mechanism that protects us from infections, viruses, and abnormal cells like cancer. It works through a network of white blood cells, mainly T cells, which detect and attack anything that seems harmful. However, cancer cells are clever — they can hide from the immune system by mimicking normal cells or producing signals that suppress immune activity. Immunotherapy helps overcome these barriers by training and empowering the immune system to identify and destroy cancer cells more effectively. Role of the Immune System The immune system recognizes harmful invaders through antigens , which are unique proteins found on the surface of cells. When a T cell detects abnormal antigens, it activates an immune response to kill the infected or damaged cell. Cancer cells often develop mechanisms to avoid detection — for example, by producing proteins that deactivate T cells or by creating an immune-suppressive environment around the tumor. Immunothera...

How Does Targeted Therapy Work to Fight Cancer Cells?

Image
  Targeted therapy is a modern cancer treatment that focuses only on the cancer cells while protecting most healthy cells. Every cancer cell has certain changes or mistakes in its genes that make it grow and spread quickly. Targeted therapy finds these specific changes and blocks them, stopping the cancer from getting bigger or moving to other parts of the body. If you are looking for a Targeted Therapy Cancer Treatment Doctor Delhi , this approach is one of the most advanced options that many cancer specialists now recommend. Unlike chemotherapy, which attacks all fast-growing cells, targeted therapy goes straight to the main cause of cancer growth. Because of this focused action, it often has fewer side effects and helps patients recover better. This treatment brings new hope to many people by making cancer care more effective and comfortable. 2. How Targeted Therapy Fights Cancer Cells Targeted therapy controls or destroys cancer cells in different ways. Here’s how it works: Fi...
