关于口腔癌

An estimated 49,670 people will be diagnosed with oral cavity cancer ororopharyngeal cancer2017年,根据 American Cancer Society 。这些案件中的9,700个将是致命的。

口腔癌可以影响口腔或口腔的任何工作部件,包括:

  • 嘴唇
  • 嘴唇和脸颊的组织
  • 牙齿
  • front two-thirds of the tongue (the back third of the tongue, or base, is considered part of the oropharynx, or throat)
  • 牙龈
  • area of the mouth underneath the tongue, called the floor
  • 嘴屋顶

When should you worry about a bump, sore, or swelling in your mouth? Here’s what to look for.

覆盖口腔,舌头和嘴唇表面的扁平细胞称为鳞状细胞。大多数口腔癌症在这些细胞中开始。舌头上的贴片,牙龈,扁桃体或嘴里的衬里可以发出麻烦。

嘴里或嘴唇内的白色或红色贴片可能是一个潜在的标志squamous cell carcinoma

口腔癌如何看起来有很多范围。皮肤可能感觉较厚或结节,或者可能存在持续的溃疡或侵蚀。重要的是要注意这些异常的持续性。非癌症病变往往在几周内解决。

口腔中的红色和白色斑块的混合物称为erythroleukoplakia,是一种异常的细胞生长,更可能成为癌症。如果红色和白色补丁持续超过两周,你应该看到你的牙医。在感受到它们之前,你可能会看到这些嘴巴异常。在早期阶段,口腔癌可能不会导致疼痛。

嘴里的明亮红色贴片,看起来并感到天鹅绒般称为红斑狼疮。他们往往是癌前的。

75%至90%的病例 erythroplakia癌变,所以不要忽略任何vividly colored spots in your mouth. If you have erythroplakia, your dentist will take a biopsy of these cells.

嘴里或嘴唇内的白色或灰色贴片被称为leukoplakia, or keratosis. An irritant like a rough tooth, broken denture, or tobacco can cause cell overgrowth and produce these patches.

The habit of chewing the inside of your cheek or lips can also lead to leukoplakia. Exposure to carcinogenic substances can also cause these patches to develop.

These patches signal that the tissue is abnormal and can become malignant. However, in most cases it will be benign. The patches may be rough and hard and difficult to scrape off. Leukoplakia generally develops slowly, over a period of weeks or months.

你可能会在嘴里的任何地方都能在嘴巴中找到erythloplakiaoccurs most oftenin the floor of the mouth underneath the tongue or on your gums behind your back teeth.

每月仔细检查一下嘴巴的任何异常迹象。在明亮的灯光下使用放大镜以获得清晰的视图。

用干净的手指轻轻拉出舌头并检查下面。看看舌头的两侧和你脸颊的内部,并在内部和外面检查你的嘴唇。

Know how to distinguish a溃疡疼痛from something more serious. A canker sore inside your mouth often burns, stings, or tingles before it’s visible. In the early stages, mouth cancer rarely causes any pain. Abnormal cell growth usually appears as flat patches.

溃疡疼痛看起来像一个溃疡,通常是在中心的萧条。溃疡的中间疼痛可能看起来是白色的,灰色或黄色,边缘是红色的。

溃疡疮通常是痛苦的,但它们并非恶性。这意味着他们不会癌症。溃疡疮通常在两周内愈合,所以嘴里的任何疼痛,肿块或斑点都需要更长的痛苦需要专业的评估。

每年两次定期牙科检查是一个重要的癌症筛查工具。这些访问使您的牙医有机会在最早的阶段检测口腔癌症的任何迹象。促进治疗减少了癌前细胞将恶化的可能性。

您还可以通过避免烟草制品,包括“蘸”或“咀嚼”和香烟,减少您开发口腔癌的风险,这些产品已与口腔癌相关联。
