Kanser Serviks
Kanser serviks di Malaysia menyumbang 12.9% daripada semua kanser wanita, dengan kadar insiden tertinggi dalam kumpulan umur 60-69 tahun. Jangkitan human papillomavirus (HPV) adalah penyebab utama kanser serviks dan risiko meningkat dengan faktor seperti merokok dan hubungan seksual awal. Pap smear disarankan untuk mengesan kanser awal dan dapat mengurangkan risiko dengan pemeriksaan berkala.

Editor's Notes
- #18 Next, we examine the progression of HPV infection to cervical cancer. After exposure to HPV, events in the viral life cycle are initiated, with specific activity regulated by the factors responsible for the host’s immune response. HPV infection alone is not sufficient to induce an immediate carcinoma because malignant tumors develop only after HPV-induced lesions persist for several months or even years. There is a large reservoir of HPV infection in young women in their teens and twenties. Only a few of these women go on to develop persistent HPV infection. Progression depends on viral type, immunologic factors and possibly co-carcinogens. Persistent high-risk infections can lead to cellular deregulation. Over time, this cellular deregulation can cause high-grade cervical lesions and ultimately, cervical cancer. Oncogenic activity has been attributed to the viral oncoproteins E6 and E7, which are crucial for malignant transformation of HPV associated cancers. In non-malignant cells, inter- and intra- cellular signals suppress these oncogenes at the transcriptional level thus limiting malignant progression. The E6 and E7 viral proteins interfere with cellular proteins that are involved in cell cycle control. They cause the human cell to experience disturbed physiologic function and genetic instability. Mutations in cellular genes devoted to the intracellular surveillance of HPV infections, integration of viral DNA, and deletions or mutations of viral transcription control sequences lead to a significantly increased expression of the E6/E7 genes, which is a consistent characteristic of high-grade intraepithelial neoplasia and cancers.6
