Brain metastasis: neurological symptoms such as headaches, [10] seizures, [10] and vertigo [10] Although advanced cancer may cause pain, it is often not the first symptom. Some patients, however, do not show any symptoms. [10] When the organ gets a metastatic disease it begins to shrink until its lymph nodes burst, or undergo lysis.
The term benign in more general medical use characterizes a condition or growth that is not cancerous, i.e. does not spread to other parts of the body or invade nearby tissue. Sometimes the term is used to suggest that a condition is not dangerous or serious. [4] Malignancy in cancers is characterized by anaplasia, invasiveness, and metastasis. [5]
Symptoms of cancer metastasis depend on the location of the tumor. When cancer begins, it produces no symptoms. Signs and symptoms appear as the mass grows or ulcerates. The findings that result depend on cancer's type and location. Few symptoms are specific. Many frequently occur in individuals who have other conditions.
Micrograph showing a colorectal carcinoma metastasis to the cerebellum. HPS stain. A brain metastasis is a cancer that has metastasized (spread) to the brain from another location in the body and is therefore considered a secondary brain tumor. [1] [2] The metastasis typically shares a cancer cell type with the original site of the cancer. [3]
CNS metastasis is the spread and proliferation of cancer cells from their original tumour to form secondary tumours in portions of the central nervous system. [ 1 ] The process of tumour cells invading distant tissue is complex and obscure, but modern technology has permitted an enhanced detection of metastasis .
Lymph node metastasis is the spread of cancer cells into a lymph node.. Lymph node metastasis is different from malignant lymphoma.Lymphoma is a cancer of lymph node, rather than cancer in the lymph node, because lymphoma originates from the lymph node itself, instead of originating elsewhere (e.g., the breast or colon) and spreading to the lymph nodes.
