Cervical Cancer: Understanding, Causes, Spread, and Prevention

-
  Cervical cancer is one of the leading causes of cancer-related deaths among women worldwide. However, it is also one of the most preventable and treatable cancers when detected early. This blog provides an in-depth look at what cervical cancer is, why it occurs, how it spreads, and how it can be prevented. What is Cervical Cancer? Cervical cancer begins in the cells of the cervix—the lower part of the uterus that connects to the vagina. When healthy cells in the cervix undergo changes (mutations) in their DNA, they begin to grow uncontrollably and form tumors. There are two main types of cervical cancer: Squamous Cell Carcinoma: The most common type, originating in the thin, flat cells lining the outer part of the cervix. Adenocarcinoma: Develops in the glandular cells of the cervix that produce mucus. Why Does Cervical Cancer Occur? The primary cause of cervical cancer is persistent infection with human papillomavirus (HPV) . However, several other factors contribut...

 All living organisms are made up of cells. Unicellular organisms consist of a single cell that performs all basic functions. In multicellular organisms, there are millions of specialized cells. Specialized cells in multicellular organisms carry out specific functions efficiently. Different groups of cells are responsible for different specialized functions. Muscle cells in humans contract and relax for movement, nerve cells carry messages, and blood transports oxygen, food, hormones, and waste materials. In plants, vascular tissues conduct food and water throughout the plant. Multi-cellular organisms exhibit division of labor, where specific functions are carried out by clusters of cells in a definite place in the body. These clusters of cells are called tissues. Tissues are arranged and designed to maximize efficiency in performing their functions. Examples of tissues include blood, phloem, and muscle. A tissue is formed by a group of cells that are similar in structure and/or wo...

CELL STRUCTURE AND FUNCTION NCERT HIGHLIGHTS

 Cell Structure and Functions: Cytology, the Science of Cells: Let's begin with cytology, which is the scientific study of cells. It delves into the form, structure, and composition of these tiny units of life. The Cell: Life's Building Block: A cell is the fundamental structural and functional unit of life. Think of it as the building block of living organisms. In unicellular organisms like amoeba and bacteria, a single cell performs all essential life functions. Cell Theory Founders: Back in the day, Anton Von Leeuwenhoek was the first to observe and describe live cells under a microscope. Later, Robert Brown discovered something crucial, the nucleus. Cell Theory, the Bedrock of Biology: In the mid-19th century, Matthias Schleiden and Theodore Schwann put forth the cell theory. It stated that all living organisms are made up of cells and their products. Furthermore, they emphasized that all cells come from pre-existing cells. This theory was later refined by Rudolf Virchow. ...
