what kills cancer cells in the body naturally
Cancer stem cells are a special group of cancer cells. They are linked to cancer recurrence, spreading, and not responding to drugs. A study found that these cells cause most cancer deaths.
It’s important to know how to target cancer stem cells for better cancer treatment. Scientists are looking for natural ways to get rid of these cells.

Cancer stem cells are key in starting, growing, and coming back in cancer. They can make new tumors because they can renew themselves and change into different cells. These cells are a special group of cancer cells that act like normal stem cells.
Cancer stem cells can renew themselves and change into different cells. This makes tumors diverse. They start and grow cancer, and can make it come back after treatment. Scientists have found markers like CD44, CD133, and ALDH1 to find and study these cells.
Key characteristics of cancer stem cells include:
Cancer stem cells can keep the tumor going by regenerating. Regular cancer cells grow and make up most of the tumor but can’t keep it going forever. Cancer stem cells are more flexible and can survive in tough conditions, including during treatment.
“Cancer stem cells are a small subpopulation of cancer cells that have the ability to self-renew and differentiate, contributing to cancer progression and recurrence.”

It’s important to target cancer stem cells in cancer treatment. They start, grow, and make cancer come back. Getting rid of them is key to stopping cancer from coming back. Scientists are working on finding ways to kill these cells to improve treatment results.
Strategies to target cancer stem cells include:
Cancer stem cells are a big problem for traditional cancer treatments. Even with new medical tech and treatment plans, getting rid of these cells is hard.
Chemotherapy is a key part of cancer treatment, aiming at fast-growing cancer cells. But cancer stem cells grow slowly or not at all. They also have ways to avoid chemotherapy, like using ABCG2 to push drugs out.
A study in the Journal of Clinical Oncology found that cancer stem cells make treatment harder. They are linked to a bad prognosis and resistance to treatments.
“Cancer stem cells are thought to be responsible for cancer recurrence and metastasis due to their ability to survive conventional treatments.”
| Mechanism | Description | Impact on Chemotherapy |
| Drug Efflux Pumps | Proteins that expel drugs from cells | Reduces intracellular drug concentration, making chemotherapy less effective |
| Quiescence | State of cellular dormancy | Chemotherapy targets rapidly dividing cells, sparing quiescent cancer stem cells |
| DNA Repair Mechanisms | Enhanced ability to repair DNA damage | Increases resistance to DNA-damaging chemotherapeutic agents |
Radiation therapy is used to fight cancer. It works well on most tumor cells but not on cancer stem cells. These cells can fix DNA damage and resist radiation.
When treatments don’t get rid of cancer stem cells, cancer can come back. These cells can survive and grow back, sometimes more aggressively. It’s important to understand how they resist treatment to find better ways to fight cancer.
Scientists are studying cancer stem cells to find new treatments. They’re looking for ways to target these cells directly. This could lead to more effective treatments that can overcome cancer stem cell resistance.
The body has many ways to fight cancer. It uses different cell processes to help fight the disease. Knowing these ways is key to making treatments that work with the body’s own defenses.
The body has several ways to fight cancer. It uses the immune system, apoptosis, and autophagy. These work together to find and kill cancer cells before they grow into tumors.
Key Natural Anti-Cancer Mechanisms:
The immune system is very important in fighting cancer. It finds and kills cancer cells. Cells like T cells and natural killer cells are key in this fight, recognizing and destroying cancer cells.
“The immune system is our most powerful ally in the fight against cancer, capable of recognizing and eliminating cancer cells through complex mechanisms.”
Apoptosis and autophagy are key in getting rid of cancer cells. Apoptosis is programmed cell death that removes damaged cells. Autophagy breaks down and recycles cell parts, keeping cells healthy.
| Process | Description | Role in Cancer Prevention |
| Apoptosis | Programmed cell death | Eliminates damaged or cancerous cells |
| Autophagy | Cellular self-digestion | Maintains cellular homeostasis, preventing cancerous transformations |
Anti-angiogenesis stops new blood vessels from forming. This cuts off the nutrients and oxygen tumors need to grow. Without these, tumors can’t grow or spread.
Natural Compounds with Anti-angiogenic Properties:
These natural compounds can help prevent cancer by stopping new blood vessels. This starves tumors of what they need to grow.
