What is cancer?
Cancer is a group of many related diseases. All cancers begin in cells, the building blocks that make up tissues. Cancer that arises from organs and solid tissues is called a solid tumor. Cancer that begins in blood cells is called leukemia, multiple myeloma, or lymphoma.
Normally, cells grow and divide to form new cells as the body needs them. When cells grow old and die, new cells take their place. Sometimes this orderly process goes wrong. New cells form when the body does not need them, and old cells do not die when they should.
The extra cells form a mass of tissue, called a growth or tumor. Tumors can be either benign (not cancerous) or malignant (cancerous). Benign tumors do not spread to other parts of the body, and they are rarely a threat to life. Malignant tumors can spread (metastasize) and may be life threatening.
What is metastasis, and how does it happen?
Metastasis means the spread of cancer. Cancer cells can break away from a primary tumor and enter the bloodstream or lymphatic system (the system that produces, stores, and carries the cells that fight infections). That is how cancer cells spread to other parts of the body.
When cancer cells spread and form a new tumor in a different organ, the new tumor is a metastatic tumor. The cells in the metastatic tumor come from the original tumor. This means, for example, that if breast cancer spreads to the lungs, the metastatic tumor in the lung is made up of cancerous breast cells (not lung cells). In this case, the disease in the lungs is metastatic breast cancer (not lung cancer). Under a microscope, metastatic breast cancer cells generally look the same as the cancer cells in the breast.
Where does cancer spread?
Cancer cells can spread to almost any part of the body. Cancer cells frequently spread to lymph nodes (rounded masses of lymphatic tissue) near the primary tumor (regional lymph nodes). This is called lymph node involvement or regional disease. Cancer that spreads to other organs or to lymph nodes far from the primary tumor is called metastatic disease. Doctors sometimes also call this distant disease.
The most common sites of metastasis from solid tumors are the lungs, bones, liver, and brain.. Some cancers tend to spread to certain parts of the body. For example, breast cancer commonly spreads to the bones, lungs, liver, or brain. However, cancers can spread to other parts of the body as well.
How does a doctor know whether a cancer is a primary or a metastatic tumor?
To determine whether a tumor is primary or metastatic, a pathologist (a doctor who identifies diseases by studying cells and tissues under a microscope) examines a sample of the tumor under a microscope. In general, cancer cells look like abnormal versions of cells in the tissue where the cancer began. Using specialized diagnostic tests, a pathologist is often able to tell where the cancer cells came from. Markers (a diagnostic indication that disease may develop) or antigens (a substance that causes the immune system to make a specific immune response) found in or on the cancer cells can indicate the primary site of the cancer.
Metastatic cancers may be found before or at the same time as the primary tumor, or months or years later. When a new tumor is found in a patient who has been treated for cancer in the past, it is more often a metastasis than another primary tumor.
Symptoms
Some people with metastatic cancer do not have symptoms. Their metastases are found by x-rays and other tests, such as MRIs, CT Scans, and PET Scans, performed for other reasons.
When symptoms of metastatic cancer occur, the type and frequency of the symptoms will depend on the size and location of the metastasis. For example, cancer that spreads to the bones is likely to cause pain and can lead to bone fractures. Cancer that spreads to the brain can cause a variety of symptoms, including headaches, seizures, and unsteadiness. Shortness of breath may be a sign of lung involvement. Abdominal swelling or jaundice (yellowing of the skin) can indicate that cancer has spread to the liver.
Sometimes a person’s primary cancer is discovered only after the metastatic tumor causes symptoms.
