Is radiation more harmful to normal cells than to cancerous cells?
Radiation can harm both normal and cancerous cells, but because cancerous cells are often more sensitive to radiation, they may be more likely to be damaged or killed by radiation therapy. Normal cells can repair themselves more effectively than cancerous cells, which helps protect them from the effects of radiation.
What is the relationship between cancerous cells and a tumor?
Cancerous cells are cells that have undergone genetic mutations that cause them to grow and divide uncontrollably. These cells can form a mass of tissue called a tumor. Tumors can be either benign or malignant. Benign tumors: These tumors are non-cancerous and typically do not invade nearby tissues or spread to other parts of the body. They may grow slowly and often have well-defined borders. Malignant tumors: These tumors are cancerous and can invade nearby tissues and spread to other parts of the body through a process called metastasis. Malignant tumors can be further categorized based on their tissue of origin (e.g., carcinoma, sarcoma, lymphoma, leukemia). So, cancerous cells are the cells that make up malignant tumors, whereas benign tumors are made up of non-cancerous cells. The distinction between benign and malignant tumors is crucial for determining treatment strategies and assessing prognosis.
How do phagocytes recognize cancerous cells from healthy cells?
Phagocytes recognize cancerous cells through differences in surface markers, such as altered proteins or glycoproteins that are often overexpressed or mutated in tumors. These abnormal markers can trigger immune responses, allowing phagocytes to identify and engulf the cancerous cells. Additionally, cancer cells may lack certain "self" markers that healthy cells possess, making them more recognizable as foreign by the immune system. Through these mechanisms, phagocytes play a crucial role in detecting and eliminating cancerous cells.
Can some RNA and DNA viruses change healthy cells into cancerous cells?
true
Which type of cells are responsible for screening and destroying cancerous cells?
Cytotoxic T cells, a type of white blood cell, are mainly responsible for identifying and destroying cancerous cells. These immune cells can recognize abnormal cells by detecting specific markers on their surface and initiate a targeted attack to eliminate them. Additionally, natural killer cells also play a role in identifying and eliminating cancerous cells through their cytotoxic activity.
Will normal or cancerous cells have a higher growth rate?
the cancerous cells
Since a virus attacks cells at random why can't we just inject a virus into a localized area of the body with cancer and let the virus wipe the cancer out?
Because then the virus would infect the cancerous cells and any nearby healthy cells. Scientists are researching technology that utilizes lasers and nano-bots to attack cancerous cells and destroy them.
What cells are more cancerous?
Brain cells
Scientists think cancer begins when?
Scientists actually believe that cancerous cells are constantly forming in our bodies. However, under normal circumstances, these cells either die on their own, usually through a process called apoptosis, or are cleared by our immune systems. These cancerous cells form as a result of epigenetic or genetic changes within the cell. If these changes result in the cells being resistant to apoptosis and our immune systems, tumors begin to form.
What is the medical term meaning lump of cancerous cells?
A carcinoma is a cancerous tumor.
Is a disease in which cells grow and divide uncontrollably?
Cancerous Cells
Which is the process of cancerous cells spreading to other body cells cells?
metastasis
