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.

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 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 are the key differences between cancer tissue and normal tissue in terms of their cellular composition and behavior?
Cancer tissue differs from normal tissue in terms of its cellular composition and behavior. Cancer cells grow uncontrollably, invade surrounding tissues, and can spread to other parts of the body. They also have genetic mutations that drive their abnormal growth. In contrast, normal cells have controlled growth, specific functions, and do not invade other tissues. Additionally, normal cells have intact cell cycle regulation mechanisms, while cancer cells have disrupted cell cycle control.
What two features does scar tissue lack that normal tissue have?
Scar tissue differs from normal body tissues in that it lacks hair follicles and melanocytes which produce pigment.
What is the name of the technique in individual layers of cancerous tissue are removed and examined under a microscope one at a time until all cancerous tissue has been removed?
This technique is called Mohs surgery. It is a precise surgical technique used to treat skin cancer by removing thin layers of cancer-containing skin and examining them under a microscope until all cancerous cells are removed.

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 %
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 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.
Can dense breast tissue kill you?
Yes if it cancerous and untreated
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.

What is the biology definition for Tumor?
Cancerous. The opposite of benign
What does Kaposi mean?
Kaposi's sarcoma is a cancerous tumour of the connective tissue.
How are cervical tissue samples examined for cancer?
The tissue sample will then be examined under a microscope for the presence of cancerous cells.
What is a surgery in which a wedge-shaped piece of cancerous lung tissue is removed?
Lobectomy
