timesofummah.com – How Cancer Can Spread to Other Body Tissues. Cancer is a disease characterized by rapid and uncontrolled cell growth. These malignant cells can damage the normal cells around them.
In its early stages, cancer usually grows in one place. However, as the cancer continues to grow and develop, it can spread to more distant parts of the body. So, how can cancer spread to other body tissues?
1. Cancer cells
Healthline explains that the body is composed of trillions of cells. Normally, cells that are old or damaged will die and then be replaced by new cells.
Sometimes, the cell’s DNA is damaged so that the cell becomes abnormal. The immune system is generally able to overcome a number of abnormal cells from further damage.
If the immune system cannot overcome abnormal cells, then the abnormal cells continue to grow. Uncontrolled growth causes abnormal cells to invade surrounding tissue. There are more than 100 types of cancer which are named according to the tissue or organ they originate from.
2. Cancer cells can spread to other parts of the body
Cancer Research UK explains that the initial location of the formation of cancer cells is called the primary cancer. These cancer cells can spread to other parts of the body. Furthermore, the separate cells can grow and form tumor cells in different parts of the body. Reported by the National Cancer Institute, the process of spreading cancer cells to other parts of the body is called metastasis.
When examined, cancer cells that grow in new tissues have the same characteristics as the primary cancer cells. Therefore, these cancer cells are called the same as primary cancer cells. For example, breast cancer that spreads to the lungs is still called metastatic breast cancer, not lung cancer even though it has spread to other parts of the body.
3. How can cancer spread to other tissues?
Unlike normal cells, cancer cells do not stick together. Cancer Research UK explains that cancer cells can also produce substances that stimulate cancer cells to move. This makes cancer cells have the ability to grow outside the body where they should.
In short, escaping cancer cells can spread to other parts of the body through the blood vessels or the lymphatic system. Furthermore, these cells grow to form tumor tissue in other parts of the body.
The process when moving to other body tissues is very complex and cancer cells generally experience death. However, under certain conditions, cancer cells can survive so they can form tumors in different body tissues.
4. Common types of cancer experience metastases
According to the Cleveland Clinic, there are several cancers that most commonly experience metastases, namely:
- Breast cancer.
- Prostate cancer.
- Lung cancer.
- Kidney cancer.
- Thyroid cancer.
- Colon cancer.
- Pancreatic cancer.
- Bone cancer.
- Heart cancer.
5. Where do cancer cells most often spread?
Cancer can spread to almost any part of the body. However, there are tissues that most often become places for cancer cells to spread. According to the National Cancer Institute, these tissues include bone, liver and lungs.
Metastatic cancer has the same characteristics as cancer in the initial tissue where it grows. Therefore, the treatment of metastatic cancer may depend on the initial location of the cancer or primary cancer.
Cancer can spread to other parts of the body which is called metastasis. This is because cancer cells are able to break away and spread to other body tissues through the blood vessels or the lymphatic system. When these cells survive, they grow to form tumor tissue in the new tissue.
