筛查规划仅对某些类型而非所有类型的癌症有效,而且一般来说,筛查规划比早期诊断复杂得多并需要更大量的资源,包括需要特殊设备和专门人员。即使建立了筛查规划,早期诊断规划也依然必要,以便查明那些发生在不符合筛查的年龄或风险因素标准的人群中的癌症病例。

癌症多采用综合治疗,以外科手术、化疗、放疗相结合为主,有需要者可结合靶向治疗、生物治疗等方法,以提高预后。
有癌症家族史、癌症相关疾病者应定期入院检查,以发现早期病变;如发现局部肿块时,应尽早就医明确病变性质并给予治疗;已明确患有癌症者,在突发出血、剧烈疼痛、呼吸困难等症状时,应紧急入院救治,以免危急生命。
確診為癌症後就要進一步做癌症屬於哪一期之分期檢查,觀察是否有轉移,並定期追蹤以免癌症復發,以便醫師擬定治療方向。(延伸閱讀:癌症診斷的目的與方法)
二级预防是指癌症一旦发生,如何在早期阶段发现并予以及时治疗。包括:①对癌症危险信号(如持续性消化不良、绝经后阴道流血、大小便习惯改变、久治不愈的溃疡等)的认识和重视;②对高发区和高危人群定期检查;③发现癌前病变并及时治疗;④加强对易感人群的监测;⑤肿瘤自检(对身体暴露部位定期进行检查)。
Palliative 癌症 care is remedy that tries to aid the affected individual truly feel superior and could be coupled with an attempt to deal with the cancer. Palliative care involves motion to lessen Actual physical, emotional, spiritual and psycho-social distress.
