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...

 AIM : To perform and observe the action of heat on ferrous sulfate crystals and classify the reaction. Materials Needed Ferrous sulfate crystals (FeSO₄·7H₂O), Bunsen burner, Test tube, Test tube holder, Safety goggles, Heat-resistant mat or stand. THEORY Ferrous sulfate (FeSO₄·7H₂O) is a blue-green crystalline compound. When heated, it undergoes dehydration and decomposition. The action of Heat on Ferrous Sulfate Dehydration: Reaction:   ​ FeSO 4 .7H 2 O(s)   →(heat)   FeSO 4 (s) + 7H 2 O Observation: The green crystals lose water and turn white. Type of Change: Physical change (loss of water). Decomposition: Reaction: 2FeSO 4 (s)      →(heat)           Fe 2 O 3 (s)      +  SO 2 (g) + SO 3 (g) ​ Observation: The white powder turns brown, releasing sulfur dioxide (SO₂) and sulfur trioxide (SO₃) gases. Type of Change: Chemical change (formation of new substances). PROCEDURE S...
