डाक्टरका अनुसार अहिले एक सय किसिमका क्यान्सर देखिएका छन् । महिलामा सबैभन्दा बढी स्तन र पाठेघरको क्यान्सर हुन्छ । पुरुषहरूमा मुख, घाँटी, फोक्सोको क्यान्सर । बालबालिकालाई रगत र आँखाको क्यान्सरले बढी सताउँछ । पुरुषमा हुने अधिकांश क्यान्सर सुर्ती तथा सुर्तीजन्य पदार्थको सेवनले हुन्छ । बालबालिकामा जेनेटिक क्यान्सर देखिएको छ ।‘
‘महिलामा ‘धेरै जनासँग यौनसम्पर्क गर्दा पाठेघरको क्यान्सर हुन्छ । असुरक्षित यौनसम्पर्क पनि क्यान्सरको अर्को कारण हो । टिनएज नकाट्दै (बीस वर्षमुनि) यौनसम्पर्क गरे क्यान्सरले झन् च्याप्छ ।‘ डाक्टरसाबले सरसर्ती भने, ‘यौनसम्पर्क नगर्दा पनि क्यान्सर हुन्छ ।‘ टिनएज पार गरेपछि यौनसम्पर्क नगर्ने हो भने क्यान्सर हुन्छ,’ ‘प्राकृतिक नियमविपरीतका हरेक कामले क्यान्सर निम्त्याँउछ ।‘ टिनएजपछि यौनसम्पर्क नगर्दा महिलामा स्तन र पाठेघरको मुखको क्यान्सर हुन्छ । शारीरिक सम्बन्ध नराख्दा पाठेघरको मुखको मासु चल्न नपाउने भएकाले क्यान्सर हुन्छ । अनि, स्तन चल्न नपाए स्तनको क्यान्सर हुन्छ ।‘
Defining Cancer
Cancer is a term used for diseases in which abnormal cells divide without control and are able to invade other tissues. Cancer cells can spread to other parts of the body through the blood and lymph systems.
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer that begins in melanocytes of the skin is called melanoma.
Cancer types can be grouped into broader categories. The main categories of cancer include:
Carcinoma - cancer that begins in the skin or in tissues that line or cover internal organs. There are a number of subtypes of carcinoma, including adenocarcinoma, basal cell carcinoma, squamous cell carcinoma, and transitional cell carcinoma.
Sarcoma - cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue.
Leukemia - cancer that starts in blood-forming tissue such as the bone marrow and causes large numbers of abnormal blood cells to be produced and enter the blood.
Lymphoma and myeloma - cancers that begin in the cells of the immune system.
Central nervous system cancers - cancers that begin in the tissues of the brain and spinal cord.
