However, a benign tumour is not benign in the usual sense; the name merely specifies that it is not "malignant", i.e. cancerous. While benign tumours usually do not pose a serious health risk, they can be harmful or fatal. [2] Many types of benign tumors have the potential to become cancerous through a process known as tumor progression. For ...
Features of benign lesion are: hyperechoic, having coarse, dysmorphic or curvilinear calcifications, comet tail artifact (reflection of a highly calcified object), absence of blood flow in the nodule, and presence of cystic (fluid-filled) nodule. However, the presence of solitary or multiple nodules is not a good predictor of malignancy.
Indolent lymphoma, also known as low-grade lymphoma, is a group of slow-growing non-Hodgkin lymphomas (NHLs). [3] Because they spread slowly, they tend to have fewer signs and symptoms when first diagnosed and may not require immediate treatment. Symptoms can include swollen but painless lymph nodes, unexplained fever, and unintended weight ...
Colloid nodules, also known as adenomatous nodules [1] or colloid nodular goiter [2] are benign, noncancerous enlargement of thyroid tissue. [3] Although they may grow large, and there may be more than one, they are not malignant and they will not spread beyond the thyroid gland. Colloid nodules are the most common kind of thyroid nodule. [4]
There are several types of benign liver tumors. They are caused by either abnormal growth of neoplastic cells or in response to liver injury, known as regenerative nodules. [2] One way to categorize benign liver tumors is by their anatomic source, such as hepatocellular, biliary, or stromal. [2]: 693–704
Healthy cells become cancerous through harmful mutations in the genome. If a cell’s genome is damaged by Genetic mutations can be benign or cancerous – a new method to differentiate between ...
A lung nodule or pulmonary nodule is a relatively small focal density in the lung. A solitary pulmonary nodule (SPN) or coin lesion, [1] is a mass in the lung smaller than three centimeters in diameter. A pulmonary micronodule has a diameter of less than three millimetres. [2] There may also be multiple nodules.
A vascular tumor is a vascular anomaly where a tumor forms from cells that make blood or lymph vessels; a soft tissue growth that can be either benign or malignant. [1] Examples of vascular tumors include hemangiomas, hemangioendotheliomas, Kaposi's sarcomas, angiosarcomas, and hemangioblastomas. An angioma refers to any type of benign vascular ...
