Ubah Gaya Hidup Elak Kanser

Kira-kira satu pertiga daripada semua jenis kanser sebenarnya boleh dicegah setiap tahun jika orang ramai mengamalkan corak pemakanan yang sihat, tidak mengambil minuman beralkohol dan lebih banyak bersenam.

Pakar Kesihatan dari Institut Penyelidikan kanser Amerika Syarikat (AICR) dan Dana Penyelidikan Kanser Dunia (WCRF) percaya bahawa membuat sedikit perubahan mudah bagi gaya hidup seharian boleh mencegah kira-kira 40 peratus kanser payu dara di Britain dan Amerika Syarikat.

Begitu juga bagi beribu-ribu kes kanser usus, perut dan prostat.

"Sungguh menyedihkan apabila melihat tahun 2011 masih ramai orang yang mati akibat kanser yang sepatutnya boleh dicegah melalui diet, mengekalkan berat badan yang sihat, aktiviti fizikal dan faktor-faktor gaya hidup yang lain," kata MArtin Wiseman, Penasihat Perubatan dan Saintifik WCRF.

Menurut Wiseman, di China saja sebanyak 620,000 kes kanser atau 27 peratus boleh dicegah, manakala di AS sebanyak 35peratus atau 340,000 kes dan di Britain sebanyak 37 peratus.

Gaya hidup yang sihat juga dapat mencegah 61,000 kes kanser di Brazil dan 79,000 kes di Britain.

Penemuan WCRF tersebut disokong oleh Pertubuhan Kesihatan Sedunia (WHO) yang turut menyarankan bahawa kerap berenam boleh menghalang banyak penyakit seperti kanser, sakit jantung dan diabetes.

Kanser merupakan punca kematian utama di seluruh dunia dan insidennya terus meningkat.

Setiap tahun kira-kira 12.7 juta orang didapati menghidap kanser dan 7.6 juta orang mati disebabkan penyakit yang berbentuk kanser. Terdapat kira-kira 200 jenis kanser yang diketahui.

Mengikut Agensi Antarabangsa bagi Penyelidikan Kanser Antarabangsa (IARC), kanser akan membunuh lebih daripada 13.2 juta orang setahun menjelang tahun 2030, iaitu hampir dua kali ganda daripada jumlah yang mati pada 2008 dan majoriti kematian adalah di negara-negara yang lebih miskin.

Sementara itu dalam kenyataan berasingan, WHO yang beribu pejabat di Geneva menyebut, kadar aktiviti fizikal yang rendah menjadi punca utama kepada anggaran 21 hingga 25 peratus kes kanser payu dara dan usus, 27 peratus bagi kes diabetes dan 30 peratus kes penyakit jantung di seluruh dunia.

Timbalan Ketua Bahagian Sains WCRF, Rachel Thompson, berkata walaupun mesejnya mudah - iaitu jangan merokok, makan makanan yang baik dan mengekalkan berat badan yang sihat boleh membantu mengelak kebanyakan jenis kanser - namun ia sukar untuk difahami oleh orang ramai.

"Kita sudah cuba sebaik mungkin untuk sampaikan mesej tentang ini yang anda perlu makan dan jumlah ini yang sepatutnya anda lakukan senaman, tetapi masih sukar untuk difahami".

WHO turut menyebut bahawa individu dewasa sepatutnya melakukan senaman sederhana sekurang-kurangnya 150minit seminggu.

Ini boleh dilakukan hanya dengan berjalan kaki selama 30minit lima kali seminggu atau berbasikal ke tempat kerja setiap hari.

Dalam pada itu Ketua Yayasan Paru-Paru Sedunia, Peter Baldini juga menyeru semua kerajaan di seluruh dunia memperkenalkan undang-undang bebas rokok dan menaikkan harga rokok.

Ini kerana rokok telah membunuh berjuta-juta perokok setiap tahun dan kanser paru-paru berkaitan dengan tabiat merokok juga telah membunuh beribu-ribu orang yang tidak merokok tetapi terdedah kepada asap rokok.

Memang tidak ada peluru ajaib yang dapat menyembuhkan semua bentuk kanser, tetapi kita ada peluang dan obligasi untuk melindungi diri dan orang tersayang daripada apa juga bentuk kanser dalam apa juga cara," kata Baldini.

Gastric Cancer

Causes

Several different types of cancer can occur in the stomach. The most common type is called adenocarcinoma, which refers to the way the cancer looks under the microscope. There are several types of adenocarcinoma. Because other types of gastric cancer occur much less frequently, this article focuses on adenocarcinoma.

Adenocarcinoma of the stomach is a common cancer of the digestive tract worldwide, although it is relatively uncommon in the US. It occurs most frequently in men over 40 years old. The incidence of this form of gastric cancer is extremely high in Japan, Chile, and Iceland. The incidence of most types of gastric adenocarcinoma in the US has declined over the years. Experts think the decrease may be related to reduced intake of salted, cured, and smoked foods.

However, the incidence of adenocarcinoma in the high part of the stomach where it connects with the esophagus has increased markedly, along with an increase in cancers of the lower esophagus. The reason for this increase is unknown.

Diagnosis is often delayed by the absence of symptoms in early disease or by self-treatment of symptoms that may be common to other, less serious gastrointestinal disorders (bloating, gas, and a sense of fullness).

Risk factors for gastric cancer are a family history of gastric cancer, Helicobacter pylori infection, blood type A, a history of pernicious anemia, a history of chronic atrophic gastritis, a condition of decreased gastric acid, and a prior history of adenomatous gastric polyp.

Prevention Cancer

One of the best ways to prevent cancer is to not smoke or chew tobacco. Many cancers can be prevented by avoiding risk factors such as excessive exposure to sunlight and heavy drinking.

Cancer screenings, such as mammography and breast examination for breast cancer and colonoscopy for colon cancer, may help catch these cancers at their early, most treatable stages. Some people at high risk for developing certain cancers can take medication to reduce their risk.

Reversing The Cancer Epidemic

5 Jenayah Kolar Putih / White Collar Crime

There is an overwhelming disparity between the full force of criminal law and punishment directed at perpetrators of theft, property damage, or personal violence and the lenient civil proceedings against managers and executives of industries and their consultants who knowingly manipulate, occupational and consumer hazards of their products and processes. White collar crime legislation is needed to correct this imbalance.

In the absence of such legislative disincentives, white collar crime in the areas of environment and health safety has continued unabated and extended into global markets.
