Which type of tissue would have a higher mitotic index normal tissue or cancerous tissue?
Cancer cells have higher mitotic index because they have a mutation in the DNA so they reproduce uncontrollably and therefore divide faster which means they have a higher mitotic index. ex. In a normal lung tissue, % of cells dividing is 5% while in a cancerous lung the % of cells divding is 25 %
What else can I help you with?
When cells are not responding to normal controls over growth and division they form tissue mass known as?
When cells are not responding to normal controls over growth and division, they can form tissue masses known as tumors. Tumors can be either benign (not cancerous) or malignant (cancerous).
Can dense breast tissue kill you?
Yes if it cancerous and untreated
If tissue is documented as friable this means that the tissue is?
Friable tissue means that it is easily crumbled or broken apart. This usually indicates that the tissue is fragile, brittle, or easily disrupted.
How does a mistake in mitosis of a cell affect its tissue?
If mitosis goes wrong, cancerous cells forms.
What is A lump of cancerous tissue called?
A lump of cancerous tissue is typically referred to as a tumor. Tumors can be either benign or malignant. Benign tumors are non-cancerous growths that do not invade nearby tissues or spread to other parts of the body. Malignant tumors, on the other hand, are cancerous growths that have the potential to invade surrounding tissues and metastasize, or spread, to other parts of the body.
What are the key differences between normal tissue and cancerous tissue?
Normal tissue and cancerous tissue differ in several key ways. Normal tissue follows a controlled growth pattern, while cancerous tissue grows uncontrollably. Normal cells have specific functions and structures, while cancer cells often lack these specialized features. Additionally, normal tissue responds to signals that regulate growth and division, whereas cancerous tissue ignores these signals. Finally, normal tissue typically remains localized, while cancerous tissue can invade surrounding tissues and spread to other parts of the body.
When cells are not responding to normal controls over growth and division they form tissue mass known as?
When cells are not responding to normal controls over growth and division, they can form tissue masses known as tumors. Tumors can be either benign (not cancerous) or malignant (cancerous).
Is fibrocollagenous tissue cancerous?
Fibrocollagenous tissue itself is not cancerous; it is a type of connective tissue that provides support and structure to organs and tissues. However, cancer can develop in or around fibrocollagenous tissue, leading to tumors that may invade or disrupt its normal function. The presence of cancerous cells in connective tissue would indicate the development of a specific type of cancer, rather than the fibrocollagenous tissue itself being cancerous.
What factors might influence the magnitude of the mitotic index?
The magnitude of the mitotic index can be influenced by several factors, including the phase of the cell cycle, tissue type, and external stimuli such as growth factors or stressors. Higher mitotic indices are often observed in rapidly dividing tissues, like cancerous cells or embryonic tissues, while quiescent or differentiated cells exhibit lower indices. Additionally, environmental factors like nutrient availability, temperature, and exposure to toxins can also affect cell division rates and thus the mitotic index.
What are the key differences between cancerous tissue and normal tissue in terms of their cellular structure and behavior?
Cancerous tissue differs from normal tissue in its cellular structure and behavior. Cancer cells grow uncontrollably, invade surrounding tissues, and can spread to other parts of the body. They also have abnormal shapes and sizes, and may have genetic mutations. In contrast, normal cells have a regulated growth cycle, maintain their shape and size, and perform specific functions in the body.
Is a mastectomy a surgical removal of only the cancerous tissue?
Mastectomy is surgical removal of the whole breast. Lumpectomy is surgical removal of only the cancerous tissue.
What are normal results for a cone biopsy?
Numerous studies have indicated that cone biopsy is successful in excising all cancerous tissue in 90% of patients with cervical cancer.
What is the medical term meaning surgical removal of a breast tumor and a margin of healthy tissue?
Lumpectomy is the medical term meaning surgical removal of a tumor with a margin of healthy tissue. Mastadenoma = benign tumor of the breast. Mastocarcinoma = carcinoma (malignant cancerous tumor) of the breast. Mastectomy = surgical procedure of removing all or part of the breast.
Can dense breast tissue kill you?
Yes if it cancerous and untreated
How could you develop a procedure to identify cancerous tissue by counting the number of cells undergoing mitosis?
To develop a procedure to identify cancerous tissue based on the number of cells undergoing mitosis, you could obtain a tissue sample, stain it to highlight mitotic cells, and then count the number of cells undergoing mitosis per unit area using a microscope. An increased number of cells undergoing mitosis may indicate abnormal cell proliferation characteristic of cancer. Further validation through histological analysis and comparison with healthy tissue samples would be necessary to confirm the presence of cancer.
Is abnormal tissue development called hyperplasia?
No, abnormal tissue development is typically referred to as dysplasia. Hyperplasia is the increase in the cell number of a tissue, which can be a normal physiological response or a part of a pre-cancerous change. Dysplasia, on the other hand, refers to the abnormal growth and development of cells within a tissue.
What is the biology definition for Tumor?
Cancerous. The opposite of benign
