Solid tumors are measured either directly, if in the skin or subcutaneous tissue, or, more generally, by a radiologist on an imaging study such as PET, CT, or MRI scan. The measurements are compared to the previous known measurements. The tumor can disappear which is complete response. The tumor can grow which is progression. The tumor can decrease by at least 30% (but not disappear completely) which is partial response. The rules for this are called RECIST criteria. Usually, there are a number of tumors in any given patient and in that case, each tumor is measured and the sums of the longest dimensions are compared with the same criteria.
Tumor markers are substances, usually proteins, that are produced by the body in response to cancer growth or by the cancer tissue itself.
It is probably safe to use eyebright as an alternative treatment for a tumor. You should also probably use conventional medicine.
Calcification of a tumor in the lung after chemotherapy generally indicates a response to treatment, often suggesting that the tumor is becoming less active or is necrotic (dying). This process can occur as the body attempts to heal the affected area and may signify a transition from an aggressive tumor to a more benign state. However, it's essential to monitor the situation with imaging and follow-up, as calcification can also occur in other contexts, such as infections or previous granulomatous disease. Always consult with a healthcare provider for personalized interpretation and next steps.
probably not
1. you did just use that word in a sentence 2. if a doctor would use the word tumor in a sentence they would probably say "we need to remove the tumor from this persons body."
Probably
no. you tumor cannot go away on its own. you would probably need a neurosurgeon. sometimes they can be treated with radiation.
Thalidomide regulates the immune response by suppressing a protein, tumor necrosis factor alpha.
the phenomenon in which hypoxic (and thus radioresistant) tumor cells become more exposed to oxygen (and thus more radiosensitive) by coming into closer proximity to capillaries after death and loss of other tumor cells due to previous irradiation.
Tumor necrosis factor (TNF) is a cytokine produced to stimulate macrophages and induce cell death in cancer cells. It plays a role in the immune response against cancer by promoting inflammation and cell death in tumor cells.
Yes, an encapsulated tumor can be malignant. While many encapsulated tumors are benign, some malignant tumors can also form a capsule as a response to the surrounding tissue. The presence of a capsule does not necessarily indicate that a tumor is non-cancerous; further evaluation, such as imaging and biopsy, is required to determine the tumor's nature. Therefore, it's important to assess encapsulated tumors on a case-by-case basis.
