11. Rectal bleeding or blood in stool

直肠出血或大便带血

 

"I thought it was hemorrhoids" is one of the most common things doctors hear when diagnosing colorectal cancer. Blood in the toilet alone is reason to call your doctor and schedule a colonoscopy.

 

12. Unexplained weight loss

原因不明的体重减轻

 

If you notice the pounds coming off and you haven't made changes to your diet or exercise regime, you need to ask why. Weight loss is an early sign of colon and other digestive cancers; it's also a sign of cancer that's spread to the liver, affecting your appetite and the ability of your body to rid itself of wastes.

 

13. Upset stomach or stomachache

胃不舒服或者胃疼

 

As simple as it sounds, a good old-fashioned bellyache is what tipped off a number of lucky folks, whose doctors ordered ultrasounds and discovered early that they had tumors on their livers. Stomach cramps or frequent upset stomachs may indicate colorectal cancer; many cancer patients say their doctors thought they had ulcers.

 

14. A red, sore, or swollen breast

胸部红肿疼痛

 

Everyone knows to check for lumps in the breasts, but too often overlooked are symptoms closer to the surface, which can indicate inflammatory breast cancer. Some women described noticing cellulite-like dimpled skin on an area of the breast. Others noticed that a breast felt swollen, hot, or irritated. Red or purplish discoloration is also cause for concern. Call your doctor about any unexplained changes to your breasts.

 

15. Nipple changes

乳头变化

 

One of the most common changes women remember noticing before being diagnosed with breast cancer is a nipple that began to appear flattened, inverted, or turned sideways. "My nipple started looking like it was turned inside out," said one woman. In addition, inflammatory breast cancer also causes nipple problems, such as itchy, scaly, or crusty skin on the nipple -- so take any nipple changes seriously.

 

16. Unusually heavy or painful periods or bleeding between periods

经期非正常的大量出血或痛经、经间期出血

 

Many women reported this as the tip-off to endometrial or uterine cancer. Unfortunately, many women also said their doctors weren't responsive, overlooking or misdiagnosing their complaints as normal perimenopause. Ask for a transvaginal ultrasound if you suspect something more than routine heavy periods.

 

17. Swelling of facial features

面部肿胀

 

Some patients with lung cancer report noticing puffiness, swelling, or redness in the face. The explanation for this is that small cell lung tumors commonly block blood vessels in the chest, preventing blood from flowing freely from the head and face.

 

18. A sore or skin lump that doesn't heal, becomes crusty, or bleeds easily

皮肤肿块、疼痛、起包、容易出血

 

Most of us know to watch moles for changes that might indicate skin cancer. But other signs, such as small waxy lumps or dry scaly patches, are easier to miss. Familiarize yourself with the different types of skin cancer -- melanoma, basal cell carcinoma, and squamous cell carcinoma -- and be vigilant about checking skin all over the body for odd-looking growths or spots.

 

19. Changes in nails

指甲变化

 

Unexplained changes to the fingernails can be a sign of several types of cancer. A brown or black streak or dot under the nail can indicate skin cancer, while newly discovered "clubbing" -- enlargement of the ends of the fingers, with nails that curve down over the tips -- can be a sign of lung cancer. Pale or white nails can be an indication that your liver is not functioning properly, sometimes a sign of liver cancer.

 

20. Pain in the back or lower right side

后背疼或者右下侧疼

 

As vague as this sounds, many cancer patients say this was the first sign of liver cancer, known as one of the "silent killers" (another is ovarian cancer). Breast cancer is also often diagnosed via back pain, which can occur when a breast tumor presses backward into the chest, or when the cancer spreads to the spine or ribs.
