Definition of Malignant Tumors: Cancerous
Malignant means that the tumor is made of cancer cells, and it can invade nearby tissues. Some cancer cells can move into the bloodstream or lymph nodes, where they can spread to other tissues within the body—this is called metastasis. Cancer can occur anywhere in the body including the breast, intestines, lungs, reproductive organs, blood, and skin.
For example, breast cancer begins in the breast tissue and may spread to lymph nodes in the armpit if it's not caught early enough and treated. Once breast cancer has spread to the lymph nodes, the cancer cells can travel to other areas of the body, like the liver or bones. The breast cancer cells can then form tumors in those locations. A biopsy of these tumors might show characteristics of the original breast cancer tumor.
Differences Between Benign and Malignant Tumors::
There are many important differences between benign and malignant tumors. Some of these include:
Growth rate: Malignant tumors may grow more rapidly than benign tumors, although there are slow-growing and fast-growing tumors in either category.Ability to invade locally: Malignant tumors may invade the tissue around them. One of the most prominent hallmarks of cancer is penetration of the basal membrane that surrounds normal tissues.Ability to spread at distance: Malignant tumors may spread to other parts of the body using the bloodstream or the lymphatic system. Malignant tumors may also invade nearby tissues and send out fingers into them, while benign tumors don't. Benign tumors only grow in the place where they started.
Recurrence: Benign tumors are easier to remove by surgery as they have clearer boundaries, and as a result, they are less likely to recur. If they do recur, it is only at the original site. Malignant tumors may have spread. As a result, they are more likely to recur and may recur in other sites, such as breast cancer recurring in the lungs or bones.
Cellularappearance : When a pathologist looks at tumor cells under a microscope, it is often obvious whether they are normal, benign cells or cancerous cells. Cancer cells often have abnormal chromosomes and DNA, making their nuclei larger and darker. They also often have different shapes than normal cells. However, sometimes the difference is subtle.
Systemic effects: While there are some benign tumors that secrete hormones, such as benign pheochromocytomas, malignant tumors are more likely to do so. Malignant tumors can secrete substances that cause effects throughout the body, such as fatigue and weight loss. This is known as paraneoplastic syndrome.
Treatments: A benign tumor can usually be completely treated with surgery, although some may be treated with radiation therapy or medication. Some benign tumors are not treated as they are not posing any health risk. Malignant tumors may require chemotherapy, radiation therapy, or immunotherapy medications to eliminate cells that may be remaining or may have spread to other parts of the body.

it is the movment of cancer/tumour cells from one body parts to others.
Benign tumour - A benign tumor is not a cancerous tumor. Unlike cancer tumors, a non cancerous tumor is unable to spread throughout the body
Malignant tumour- Malignant tumors are formed from abnormal cells that are highly unstable and travel via the blood stream, circulatory system, and lymphatic system. Malignant cells do not have chemical adhesion molecules to anchor them to the original growth site that benign tumors possess
