Question

Answer

Answer

Carcinoma refers to a malignant neoplasm of epithelial origin or cancer of the internal or external lining of the body. Carcinomas, malignancies of epithelial tissue, account for 80 to 90 percent of all cancer cases. Epithelial tissue is found throughout the body.

Answer

In simple terms carcinoma is cancer in epithilial tissue and it is the most common type of cancer

Answer

Carcinoma is a category of types of cancer that develop from epithelial cells.Specifically, a carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that arises from cells originating in the endodermal, mesodermal or ectodermal germ layer during embryogenesis.Carcinomas occur when the DNA of a cell is damaged or altered and the cell begins to grow uncontrollably and become malignant.

Answer

B

Answer

Carcinoma refers to malignant tumours of skin or mucous membrane

Carcinoma is a type of cancer that originates from epithelial cells, which are the cells that line the surfaces of organs and tissues in the body. This type of cancer accounts for the majority of all cancer cases. Carcinomas can occur in various parts of the body, including the skin, lungs, breast, colon, and prostate, among others.

Malignant tumours of skin or mucous membrane
Carcinoma specifically refers to malignant tumours of the skin or mucous membrane. The skin is the largest organ in the body and is composed of different layers of cells. When the cells in the skin or mucous membrane undergo abnormal growth and division, they can form a carcinoma.

Skin carcinoma, also known as skin cancer, is a type of carcinoma that develops in the skin cells. There are different types of skin carcinoma, including basal cell carcinoma, squamous cell carcinoma, and melanoma. These carcinomas can occur due to various factors such as exposure to ultraviolet (UV) radiation from the sun, genetic mutations, and certain environmental factors.

Mucous membrane carcinomas, on the other hand, develop in the mucous membranes that line various organs and body cavities such as the respiratory tract, digestive tract, and reproductive organs. Examples of mucous membrane carcinomas include lung carcinoma, colorectal carcinoma, and cervical carcinoma.

Other options:
Option A: Malignant tumour of colon - This refers to colorectal carcinoma, which is a type of carcinoma that originates in the colon or rectum. Colorectal carcinoma is a common type of cancer, but it is not the definition of carcinoma itself.

Option C: Malignant tumour of muscular tissue - This refers to sarcoma, which is a type of cancer that originates in the connective tissues, including muscle, bone, and cartilage. Sarcoma is not considered a carcinoma.

Option D: Benign tumour of connective tissue - This refers to a benign tumour called a fibroma, which develops in the connective tissues. A fibroma is not considered a carcinoma because it is non-cancerous and does not invade nearby tissues or spread to other parts of the body.

In summary, carcinoma specifically refers to malignant tumours of the skin or mucous membrane. It is the most common type of cancer and can occur in various parts of the body.

Answer

Carcinoma is a type of cancer, that develops form epithelial cells. Specifically, it is a cancer that begins in a tissue that lines the inner or outer surfaces of the body. It occur when the DNA of a cell is damaged or altered and the cell begins to grow uncontrollably and become malignant.
So, the correct answer is 'Malignant tumours of the skin or mucous membrane'.
