Understanding Cancer
Cancer is a complex disease involving the uncontrolled growth of abnormal cells, leading to the formation of tumors and potential spread to other parts of the body. To learn more about how quercetin may offer potential benefits in cancer prevention and treatment, continue reading our comprehensive review.
What cancer is and how it develops
Cells in our body grow and divide to make more cells. This is how we heal wounds and grow. Sometimes, these cells keep dividing when they should stop. This extra cell growth can form a lump called a tumor.
Tumors can be cancerous or not cancerous.
Cancer happens when these cancerous cells spread around the body. They invade other parts of the body and harm normal cells. This process is called metastasis. Cancer can start almost anywhere in the human body, which is made up of trillions of cells.
Over time, genetic changes can turn on certain genes and turn off others in a cell. That changed cell gains the ability to keep growing without control or order, making more cells just like it and forming a tumor.
A tumor can grow and invade tissue around it. And as cancer cells travel through the bloodstream or lymph system to reach other organs, they start new tumors there if not stopped early.
These bad behaviors are what makes some cancers so serious.
Common types of cancer
Cancer is a disease where cells in the body grow out of control. Certain types of cancer are more common than others.
- Breast Cancer: This cancer starts in the breast tissue. It’s one of the top cancers among women, but men can get it too. Breast cancer cells may form tumors that can be felt as lumps.
- Lung Cancer: Smokers have a higher risk for this type of cancer, but non-smokers can also develop lung cancer. There are two main types: small cell and non-small cell lung cancer.
- Prostate Cancer: Found only in men, this cancer grows in the prostate gland which makes some of the fluid in semen. It often grows slowly.
- Colorectal Cancer: This includes cancers that start either in the colon or the rectum. It often begins as polyps, which are little growths inside the colon or rectum.
- Skin Cancer: The most common kind is called basal cell carcinoma. The sun’s UV rays can damage skin and lead to skin cancer.
- Ovarian Cancer: Only women have ovaries, so only they can get this cancer. It might not cause early symptoms but can be very serious.
- Pancreatic Cancer: This type starts in your pancreas, which helps you digest food and manage your blood sugar. Pancreatic cancer is often hard to find early.
Quercetin’s Role in Cancer Prevention and Treatment
Quercetin may affect cancer cells by inhibiting their growth and promoting apoptosis, as evidenced by laboratory and animal studies, suggesting its potential in cancer prevention and treatment.
To learn more about the promising effects of quercetin in oncology, keep reading.
Mechanisms by which quercetin might affect cancer cells
Quercetin affects cancer cells by triggering programmed cell death, known as apoptosis. It also stops the growth and replication of cancer cells and causes them to self-destruct. This is achieved through the activation of caspase 3, 8, and PARP cleavage, as well as inducing cell cycle arrest.
Furthermore, quercetin can enhance apoptosis and autophagy in cancer cells by inhibiting the phosphorylation of Akt, mTOR, and ERK while reducing beta-catenin levels.
Quercetin also collaborates with chemotherapy and radiotherapy to enhance treatment sensitivity while safeguarding healthy cells from harmful effects. Its ability to regulate the cell cycle coupled with its antioxidant properties makes it a potential candidate for use in cancer treatment strategies.
