The symptoms of metastatic cancers depend on the tumor location and can include enlarged lymph nodes (which can be felt or sometimes seen under the skin and are typically hard), enlarged liver or enlarged spleen, which can be felt in the abdomen, pain or fracture of affected bones and neurological symptoms.Common environmental factors that contribute to cancer death include tobacco (25–30%), diet and obesity (30–35%), infections (15–20%), radiation (both ionizing and non-ionizing, up to 10%), stress, lack of physical activity and pollution.

Oncoviruses (viruses that can cause cancer) include human papillomavirus (cervical cancer), Epstein–Barr virus (B-cell lymphoproliferative disease and nasopharyngeal carcinoma), Kaposi's sarcoma herpesvirus (Kaposi's sarcoma and primary effusion lymphomas), hepatitis B and hepatitis C viruses (hepatocellular carcinoma) and human T-cell leukemia virus-1 (T-cell leukemias).

Bacterial infection may also increase the risk of cancer, as seen in Helicobacter pylori-induced gastric carcinoma.

The findings that result depend on the cancer's type and location. Many frequently occur in individuals who have other conditions. Thus, it is common for people diagnosed with cancer to have been treated for other diseases, which were hypothesized to be causing their symptoms.

Local symptoms may occur due to the mass of the tumor or its ulceration.

You can't control everything; leave it to God and just say, "Okay, this is my journey." This whole thing has been such a gift.

I didn't think I deserved it,' the pretty presenter explained.

Sources of ionizing radiation include medical imaging and radon gas.Ionizing radiation is not a particularly strong mutagen.Medical use of ionizing radiation is a small but growing source of radiation-induced cancers.Ionizing radiation may be used to treat other cancers, but this may, in some cases, induce a second form of cancer.Excepting the rare transmissions that occur with pregnancies and occasional organ donors, cancer is generally not a transmissible disease.
