Cancer treatment involves different approaches designed to remove, control, or slow the growth of cancer, depending on the type and stage of the disease. These approaches usually work best and help your body recover. But there are times when the treatment you thought might work stops working. This happens because cancer cells adapt to the treatment environment and find new ways to survive in your body.
What is drug resistance?
The treatment you are going through may kill cancer cells in the beginning, but some cells can still find a way to survive. These cancer cells can then adapt to the treatment environment you are going through. This is when they start resisting the treatment drugs and start to mutate, and you might face a cancer relapse. At this point, your treatment can become ineffective as these cancerous cells have adapted to your body’s condition and strengthened themselves accordingly.
How is this resistance caused?
There is no single cause for drug resistance. The resistance conditions may vary depending on how these cancer cells adapt to your body and mutate.
Genetic changes in your body can allow cancer cells to mutate and resist drugs.
Different types of tumors can also naturally grow and resist your treatment.
Some cells can dismantle the drug you take before it begins to work in your body.
Types of drug resistance
Drug resistance can also have its types, where the way cancer cells stop the drug and mutate in your body can differ.
Intrinsic resistance can happen when some cancer cells resist your treatment naturally before the drugs even begin their work.
Acquired resistance can happen when cancer cells adapt to your body and drugs over time, which can cause the therapy to fail.
What are the challenges?
The cancer cells can start their mutation once they find a way to adapt to your body. It doesn’t matter if you continue your medications; cancer will keep growing as it destroys the effectiveness of the drug even before it starts its work. This can be really concerning, as cancer can progress and also spread to different organs of your body.
Ways to tackle drug resistance
Drug resistance is indeed a challenge when your body doesn’t respond to your ongoing treatment. But modern-day oncology has some ways that can stop cancer from mutating. There are approaches like combination therapy and targeted therapy that can use multiple drugs and target cancer cells precisely to stop their mutation. Personalized medicine can also help to destroy these cancer cells based on your health profile. A study published by the National Library of Medicine in August 2024 shows the number of new techniques through which drug resistance can be stopped without harming your body.
Staying hopeful for recovery
Feeling disappointed is normal when your treatment stops working in your favor. But with the new research and therapies, drug resistance can be overcome. By staying hopeful, you can recover quickly with more resilience.
