Malignant tumors are cancerous (ie, they invade other sites). They spread to distant sites via the bloodstream or the lymphatic system. This spread is called metastasis. Metastasis can occur anywhere in the body and most commonly is found in the liver, lungs, brain, and bone.
Nearly all types of cancer have the potential to metastasize, but whether they do depends on a number of factors.
In some situations, metastatic cancer can be cured. But for most metastatic cancers, treatment does not cure the cancer but it can slow its growth and reduce symptoms. It is possible to live for many months or years with certain types of cancer, even after the development of metastatic disease.
There are a number of benign metastasizing tumors: benign metastasizing meningioma. benign metastasizing leiomyoma. primary adenoma of thyroid.
(muh-LIG-nunt) A term used to describe cancer. Malignant cells grow in an uncontrolled way and can invade nearby tissues and spread to other parts of the body through the blood and lymph system.
Many tumors are not cancer (they're benign). But they still may need treatment. Cancerous, or malignant, tumors can be life-threatening and require cancer treatment.
Cancer that spreads from where it started to a distant part of the body is called metastatic cancer. For many types of cancer, it is also called stage IV (4) cancer. The process by which cancer cells spread to other parts of the body is called metastasis.
Lymph nodes are one of the most common places for cancer to spread. The liver, lungs, and bones are also common sites of metastasis. Certain types of cancer are more likely to spread to certain organs. For example, prostate cancer has a tendency to spread to bones.
A patient with widespread metastasis or with metastasis to the lymph nodes has a life expectancy of less than six weeks. A patient with metastasis to the brain has a more variable life expectancy (one to 16 months) depending on the number and location of lesions and the specifics of treatment.
Many have fulminated against oncologists who lie to patients about their prognoses, but sometimes cancer doctors lie for or with patients to improve our chances of survival. Here's the back story in this case. The patient, a woman in her early 50s, was given a diagnosis of endometrial cancer.
The metastatic tumor is the same type of cancer as the primary tumor. Many cancer deaths are caused when cancer moves from the original tumor and spreads to other tissues and organs. This is called metastatic cancer.
The spread of cancer cells from the place where they first formed to another part of the body. In metastasis, cancer cells break away from the original (primary) tumor, travel through the blood or lymph system, and form a new tumor in other organs or tissues of the body.
Most malignant tumors that metastasize do so within five years after the primary tumor has been detected, so this raises the question of how one can explain “dormancy” among tumor cells for decades.
Desmoid tumor: These are often more aggressive than most benign tumors and may invade nearby tissue and organs. But they do not metastasize.
Some cancers are difficult to treat and have high rates of recurrence. Glioblastoma, for example, recurs in nearly all patients, despite treatment. The rate of recurrence among patients with ovarian cancer is also high at 85%.
Metastatic cancers have spread from where they started to other parts of the body. Cancers that have spread are often thought of as advanced when they can't be cured or controlled with treatment. Not all metastatic cancers are advanced cancers.
Your oncologist may recommend avoiding chemotherapy if your body is not healthy enough to withstand chemotherapy or if there is a more effective treatment available.
During a course of treatment, you usually have around 4 to 8 cycles of treatment. A cycle is the time between one round of treatment until the start of the next. After each round of treatment you have a break, to allow your body to recover.
Grade 4: These undifferentiated cancers have the most abnormal looking cells. These are the highest grade and typically grow and spread faster than lower grade tumors.
Lung and bronchus cancer is responsible for the most deaths with 130,180 people expected to die from this disease. That is nearly three times the 52,580 deaths due to colorectal cancer, which is the second most common cause of cancer death. Pancreatic cancer is the third deadliest cancer, causing 49,830 deaths.
1. Breast cancer. The 5-year relative survival rate for stage 0 and 1 breast cancer is 99–100 percent . Therefore, people with this stage and type of cancer are almost 100 percent as likely to survive for at least 5 years as people without the condition.
