Primary tumor: A tumor that is at the original site where it first arose. For example, a primary brain tumor is one that arose in the brain as opposed to one that arose elsewhere and metastasized (spread) to the brain.

Primary tumors
Tumors that initially arise and grow within the brain are termed primary tumors. Most adult brain cancers are not primary tumors, but are the result of primary cancer that has spread from other areas of the body.
Primary tumors: Primary tumors occur when one type of cell transforms from its normal characteristics. Once transformed, the cells grow and multiply in abnormal ways. As these abnormal cells grow, they become a mass or tumor.

Primary Tumor
A primary tumor is the first place where cancer began to grow.
The primary tumors are usually located in the pancreas or small intestine. Occasionally they are found in nearby lymph nodes. Very rarely, they can be located in more distant parts of the body such as the ovaries.
These primary tumors are named after the part of the brain or the type of brain cell from which they arise.

This is a primary tumor of the heart. It is quite rare. It usually begins in the septum between the two heart ventricles, with 80% of the tumors growing into the left atrium.
What are primary tumors?
The original tumor is called the "primary tumor." Its cells, which can break off and travel through the body, can begin the formation of new tumors in other organs. These new tumors are referred to as "secondary tumors.

Farther away from the center of the body than the primary tumor is.

T- Extent of primary tumor
T1 to T3 shows the increase in the extent or size of the tumor.
N- Involvement of nodes
N1 to N3 shows the increasing node involvement.
Other types of primary tumor include fibroma, hemangioma, myxoma, hamartoma, teratoma, lipoma, and various forms of sarcoma.
What problems do cardiac tumors cause?
in-transit metastasis (in-TRAN-zit meh-TAS-tuh-sis) A type of metastasis in which skin cancer spreads through a lymph vessel and begins to grow more than 2 centimeters away from the primary tumor but before it reaches the nearest lymph node.

Tumors that originate in the brain or spinal cord are called primary tumors. Most primary tumors are caused by out-of-control growth among cells that surround and support neurons.
Laminectomy is indicated for primary tumors that produce spinal cord or cauda equina compression; it isn't usually indicated for metastatic tumors.
With the widespread use of the microscope in the 18th century, it was discovered that the 'cancer poison' spread from the primary tumor through the lymph nodes to other sites ("metastasis").
Usually, this happens as cancer cells break away from a primary tumor and enter the bloodstream or lymphatic system. When cancer cells spread and form a new tumor in a different organ, the new tumor is a secondary or metastatic tumor (1).
The goal of surgery is to completely remove the primary tumor.
Radiation therapy. The goal of radiation therapy is to kill cancer cells using x-rays. This treatment can be used to shrink a tumor before surgery.
Enlargement of the primary tumor may obstruct the urinary tract which can lead to urinary tract infections. The tumor may cause neurological dysfunction and/or pain if it grows large enough to press on nerves lying in or near the prostate.
A malignant tumor arising from the nuclear layer of the retina that is the most common primary tumor of the eye in children.
The tumor tends to occur in early childhood or infancy and may be present at birth.
The width of normal skin included in the surgical excision depends to a certain extent upon thickness in mm of the primary tumor.
In situ superficial spreading melanoma can be treated with a 0.5 -1 cm surgical margin.
Even in early-stage breast cancer, cells may break away from the primary tumor and spread to other parts of the body (metastasize).
Tumors are considered to be either primary tumors or secondary tumors. A primary tumor is the original site of tumor growth. A secondary tumor originates from another tumor elsewhere in the body.
Definition A myxoma is a rare, usually noncancerous, primary tumor (a new growth of tissue) of the heart. It is the most common of all benign heart tumors. Description Myxoma is an intracardiac tumor; it is found inside the heart.
Sentinel nodes are a small cluster of lymph nodes to which cancer first spreads from the primary tumor.
Stages I, II, and III: These higher numbers mean the primary tumor may be bigger, the cancer has spread to nearby lymph nodes, and/or it has spread directly to organs next to the primary tumor.
Specialists at Mayo provide the latest interventions for both primary tumors and those that have spread (metastasized).
Team approach. Mayo Clinic specialists work as a team to listen, counsel and treat people who have MEN 1.
If the primary tumor can be located outside of the brain, the primary tumor is usually biopsied rather than the brain tumor.
A lumbar puncture (spinal tap) is sometimes also performed to test the cerebral spinal fluid.
The "T" status stands for the primary tumor, "N" status stands for the status of the regional lymph nodes, and the "M" status stands for the presence or absence of metastases to other organs.
Some common types of primary tumors — named after the type of brain cells from which they originate — include acoustic neuromas (schwannomas), astrocytomas, medulloblastomas, meningiomas and oligodendrogliomas.
A multicentric cancer consists of a primary tumor with satellites of cancerous growth in surrounding tissues. The basis for adjuvant radiation therapy after, for instance, a lumpectomy is to irradiate the satellite tumors, should any exist.
When cancer spreads from its original place to another part of the body, the new tumor has the same kind of abnormal cells and the same name as the primary tumor.
Surgery to remove the primary tumor followed by chemotherapy and surgery to remove cancer that has spread to other parts of the body.
A clinical trial of chemotherapy given before and after surgery, with or without biologic therapy.
Bone tumor is an inexact term, which can be used for both benign and malignant abnormal growths found in bone, but is most commonly used for primary tumors of bone, such as osteosarcoma (or osteoma).

Lynch II, Cowden, Peutz-Jeghers, or ataxia telangectasia), or ...
These secondary cancers are not a relapse or recurrent retinoblastoma, but are primary tumors (brand new tumors) of other organs. The most common secondary cancer is osteosarcoma (cancer of the bone).
When a cancerous mass makes its primary tumor, it is often a slow process. This inhibits any symptoms of the disease or illness to show forth to the patient. The later a doctor diagnoses a tumor the worse off the patient is.
Metastatic cancers are more difficult to treat than primary tumors, as the cancer has spread over a larger area. While brain surgery can cure some types of primary brain tumors, brain surgery alone will not cure secondary brain cancer.
Malignant gliomas are the most common primary tumors of the central nervous system (the brain and spinal cord). They are often resistant to treatment and carry a poor prognosis (have a dismal outlook). [MedicineNet] ...
extensive - cancer has spread beyond the primary tumor in the lung into other parts of the body.
