Tubal ligation is a surgical procedure that closes or removes the fallopian tubes to prevent pregnancy permanently. It is a highly effective form of birth control that does not use hormones. Sometimes, it is chosen by patients with certain genetic risks for ovarian or fallopian tube cancer. The procedure usually requires surgery and anesthesia and is intended as a permanent method of sterilization.

Tubefeeding

Also Known As: Gavage

Tubefeeding, also called gavage, is a way to provide medicines, fluids, or liquid nutrition through a small tube placed into the stomach or small intestine. The tube may go through the nose, mouth, or a small cut in the abdomen. It can be used alongside regular eating or as the only source of nutrition when eating by mouth is not enough or possible.

Tuberculosis

Also Known As: TB

Tuberculosis (TB) is a bacterial infection that usually affects the lungs but can stay hidden in the body for years without symptoms. In cancer care, TB may be mentioned because some treatments can weaken the immune system, increasing the risk of TB becoming active. Doctors may test for TB before or during cancer treatment and use special medicines called antituberculosis drugs if needed to keep you healthy.

Tuberous Sclerosis

Tuberous sclerosis is a rare genetic condition that causes non-cancerous tumors to grow in the brain, kidneys, skin, and other organs. It can lead to seizures, skin changes, and developmental challenges. While there is no cure, treatments can help manage symptoms and control tumor growth. Understanding how tuberous sclerosis affects each person is important for personalized care.

Tubulin

Tubulin is a protein inside cells that helps form microtubules, which are important for cell division and movement. Some cancer drugs work by targeting tubulin to stop cancer cells from dividing. These drugs are called antitubulin agents. Tubulin-related treatments are still being studied, so it’s important to ask your care team how this term applies to your specific situation.

Tubulovillous Adenoma

A tubulovillous adenoma is a type of polyp, or abnormal growth, that can develop in the colon or other parts of the digestive tract. These growths are made of gland-like tissue and have a higher chance than some other polyps of turning into cancer if not removed. It’s important to discuss what this finding means for you with your healthcare team rather than assuming it is a diagnosis or treatment plan on its own.

Tucatinib

Sometimes, debulking is done to relieve symptoms caused by the tumor pressing on organs, improving quality of life even if it doesn’t cure the cancer.

Tumor DNA Sequencing

Tumor DNA sequencing is a lab test that reads the exact order of the chemical building blocks in a tumor’s DNA. This helps doctors understand specific changes in the tumor that may guide treatment choices. Patients should discuss what the results mean for their own care with their medical team, rather than assuming the term alone gives a diagnosis or treatment plan.

Tumor Grade

Also Known As: Grade, Histologic Grade

Tumor grade describes how much cancer cells look like normal cells when viewed under a microscope. Low-grade tumors have cells that look more like normal cells and tend to grow and spread slowly. High-grade tumors have cells that look very abnormal and may grow or spread faster. Tumor grade helps doctors plan treatment and understand how the cancer might behave, but it is just one part of the overall diagnosis.

Tumor Heterogeneity

Tumor heterogeneity means that cancer cells within a tumor or between tumors in different people can be different from each other. These differences can affect how cancer is diagnosed, how it behaves, and how it responds to treatment. It’s important to talk with your care team about what tumor heterogeneity means for your specific situation rather than treating the term as a diagnosis or treatment plan.

Tumor Initiation

Tumor initiation is the first step in the process where normal cells change in a way that allows them to form tumors. Certain substances called tumor initiators, including mutagens that damage DNA, can start this process. For patients and caregivers, it’s important to understand this term in context and ask your care team how it relates to your specific situation rather than seeing it as a diagnosis or treatment plan.

Patients at risk are closely monitored and may receive medicines and fluids to help prevent problems.

Tumor Marker

A tumor marker is a substance found in blood, urine, or tissues that may suggest the presence of cancer or certain noncancerous conditions. These markers are often proteins made in higher amounts by cancer cells. Doctors use tumor markers alongside other tests to help diagnose cancer, plan treatment, monitor how well treatment is working, and check if cancer has returned. However, tumor markers alone cannot confirm cancer.

Tumor Marker Test

A tumor marker test measures substances made by cancer cells or by the body in response to cancer. These tests, often done on blood or tissue samples, help doctors diagnose cancer, guide treatment choices, and monitor how well treatment is working. Tumor marker tests are usually used alongside other tests and are not by themselves a diagnosis.

Tumor Microenvironment

The tumor microenvironment is the area around a tumor made up of normal cells, blood vessels, molecules, and support structures. It can influence how a tumor grows and spreads. Changes in this environment, including acidity and immune activity, may affect cancer behavior and treatment. Patients should ask their care team how this term relates to their specific situation rather than seeing it as a diagnosis or treatment by itself.

Tumor Model

A tumor model is a tool used in cancer research where cells, tissues, or animals help scientists study how cancer grows and how treatments might work. Special mice called athymic nude mice are often used because their weak immune systems allow human tumors to grow inside them. This helps researchers test new drugs before they are used in people. For patients, tumor models are part of research, not a diagnosis or treatment.

Tumor Mutational Burden

Also Known As: TMB

Tumor Mutational Burden (TMB) is a measure of how many genetic changes, or mutations, are found in the DNA of cancer cells.
