Early stage cancer can be seen from this part

Everyone may get cancer because we all have a "proto-oncogene" that may be activated by external stimulation. And this external factor often comes from our lives. The International Union Against Cancer once published a report stating that there are 12 million new cases of cancer each year worldwide, of which up to 40% could have been prevented through self-examination in life. The following are signs of cancer in various parts of the body.

skin

The inspection should be thorough and careful. From head to toe, carefully examine every inch of skin, including chest, hips, back, buttocks and underarms, especially don't forget hidden parts such as armpits, to observe whether there are any abnormal changes.

Check yourself to understand the birthmarks and spots on your body. Pay special attention to new spots, painful spots that don't heal in two or three months, and spots that grow larger or change color. Early-stage skin cancer spots appear flat or raised, sometimes bleeding with slight stimulation, or scab over for no reason. Especially if the scab does not disappear for a long time, it should be taken seriously.

head

First check whether the face is symmetrical, swollen, and whether the acne has increased or changed. Then check whether the whites of the eyes are yellow or red, whether the eyes are pale and lifeless, and whether the angle of the eyes is normal. Then use your index finger to gently push the tip of your nose upwards to see if there are any changes inside the nostrils, then lightly touch the outside of the nose to see if there is any swelling or abnormality. Finally, use the thumb, index finger and middle finger of both hands to gently pinch the ear to see if there is any pain or lumps.

Use your index and middle fingers to gently touch and move all the lymph node tissue around the head, including in front of the ears, under the collar, tonsils, deep neck chain, clavicle, behind the ears, occipital bone, shallow neck, back neck chain, etc. Pay attention to whether there are any abnormalities in size, shape, and contour. If there are any abnormalities, pay attention to whether there is unilateral nasal congestion, nosebleed or ear congestion, and seek medical treatment as soon as possible.

Oral

First observe whether there are any differences in the color, opening and closing mobility, and shape of the lips. Open your mouth again and check carefully to see if there are any painless red or white patches or abnormal lumps on the lips and back of the tongue. Check whether the inner cheek membranes and dental caries are red, swollen, hardened, thickened, or have spots (especially white spots). Also, stretch, retract and flip the tongue to observe whether there is vibration, asymmetry, difficulty in movement and abnormal color, and whether the surface, tip and edges of the tongue are varicose or swollen.

Secondly, use both hands to touch the parotid cheeks, submandibular area and neck to observe whether there are painless lumps or enlarged lymph nodes. The precursor symptoms of oral cancer that need to be alerted include: 1. Fixed ulcers on the oral mucosa (upper and lower lips, tongue, gums, etc.) that do not heal after 3 to 4 weeks of treatment.

breast

Women should usually perform a breast examination within a week of their menstrual period (or any other day if they have not had their menstrual period).

Take off your shirt and look in front of a full-length mirror to see if your breasts are symmetrical, if your skin is shiny and has a normal color, and if there is any venous dilation or edema. Then raise your arms and check whether the breasts on both sides are on the same level, whether the color of the areola is the same, whether there are any pitting depressions in the skin, whether there are any orange peel-like changes, whether there are regional depressions (dimple sign), whether the nipple skin is shed or eroded, and whether the nipple is elevated or retracted.

Raise both arms again and do the same check. Secondly, lie on your back, place one hand under your head, and use the five fingertips of the other hand to gently press and touch in a clockwise direction from the outside to the inside to check for any lumps, thickening or pain, alternating between the two hands. Pay attention to any abnormalities in the upper lateral and subabdominal lymph nodes.

Abdominal examination

First observe the abdominal shape, texture, color, blood vessels, hair for any abnormal changes, and the navel for any discoloration or secretions. Then lie flat on your back with your knees bent, relax your abdomen, put your fingers together and gently press your abdomen to check for any lumps or pain.

Vagina

Middle-aged and elderly men should frequently touch their groin and penis to see if there are any lumps or other abnormalities, feel the lymph nodes in the fornix, and examine the glans penis. When touching Gaojiu, you can press one side with your index and middle fingers, and the other side with your thumb. Be careful if there are any protrusions or other changes.

Secretions

Observe the color, concentration, odor and whether the sputum contains blood. Then observe whether there are any changes in urine color, flow rate, and urine volume. Secondly, look at the color of the stool, whether there are blood clots, changes in thickness, and hardness, etc.

To prevent cancer, follow 3 principles in diet

First, don’t eat it too salty. If you reduce the intake of salt and salt-pickled products and eat more fresh vegetables and fruits, the incidence of gastric cancer will decrease. Nitrite is the number one killer of tumors. Stale vegetables, pickled ham and pickles all contain this carcinogen. Under normal conditions, nitrite in the diet will not cause harm to human health. It will only cause harm to the human body when excessive nitrite is consumed and the body lacks vitamin C. If you eat too much salt, it will damage the gastric mucosa and cause nitrates to be reduced to nitrites.

Second, don’t go too far. The food that modern people eat is too refined, which greatly reduces the intake of fiber. Cellulose can absorb a large amount of water, promote intestinal peristalsis, speed up the excretion of feces, shorten the residence time of carcinogens in the intestines, reduce adverse stimulation to the intestines, and thus prevent the occurrence of colon cancer. Whole grains, oatmeal, celery, fungus, etc. are all foods rich in fiber. However, excessive intake of fiber will affect the absorption of many nutrients and reduce physical strength, so 10-30 grams per day is appropriate.

Third, don’t over-oil. Surveys show that if the intake of oil and animal protein increases, the incidence of colorectal cancer, breast cancer, prostate cancer and pancreatic cancer will increase. Frying food at high temperature will produce benzopyrene, heterocyclic amine compounds and acrylamide, which may be related to lung adenocarcinoma in women, while boiling or steaming in a microwave oven will not cause this.
