On January 14, 2016, Alan Rickman, who plays Professor Snape in Harry Potter, died of cancer at the age of 69.
Actor and director Alan Rickman, He has participated in or directed many films and television works, The most famous of them is his role as Snape in the Harry Potter movies. This is the image of a nightmare teacher in his childhood. He is not only Harry Potter’s teacher and principal, At the same time, he deeply loved Harry’s mother, Lily. After Lily was mercilessly killed by Voldemort, he buried this love in the bottom of his heart and gave it to Harry and all the students in a stern and mean way, hoping that when the real dark magic came, the students would become qualified soldiers.
I believe all fans will never forget that in the play, Snape was killed by Najib, the serpent, in order to protect all the students. Before he died, he said to Harry with thoughts and perseverance that he could not express in his life: “Look into my eyes… your eyes are very like your mother.”
Professor Snape left. He went to heaven to meet his favorite Lily. As Muggles (in the play, ordinary people are identified as Muggles), how can we gain anything from this battle between Professor Snape and Voldemort, cancer?
Everyone, may suffer from cancer [Voldemort]
Cancer, like Voldemort, who has seven horcruxes in the magical world, hides carcinogenic factors in our daily life in various ways. Smoking, drinking, irregular work and rest, lack of vitamins, etc., may all become the [horcruxes] that make Voldemort, the cancer, play a powerful role in the body.
How to detect cancer early [Voldemort]?
In the play, once Voldemort is about to commit evil, Harry’s lightning-like scar on his head will cause severe pain, reminding Harry and the Defense Against the Dark Arts camp.
In real life, once our body encounters cancer, there will also be various alarms. When the following symptoms occur, we need to go to the hospital for examination in time to rule out whether we suffer from cancer:
- Repeated cough, chest pain, shortness of breath, sputum often bloodshot; Unexplained protruding mass on the body; Abdominal pain, stool thinning and hematochezia; The nevus that has been present for a long time suddenly becomes larger in a short period of time. Hard and hard masses are felt around the breast or under the armpit. During non-lactation period, the breast secretes liquid; The position of the liver under the right rib is dull and painful for a long time. Unexplained emaciation.
Not only should we alert ourselves to these cancer signals, but we should also tell the people around us that the struggle with cancer, a powerful opponent, is a seesaw battle and is not feasible on our own.
In addition, Voldemort is not easy to be found when it is first formed, but it is very weak and can be easily destroyed. If we can form a good habit of cancer prevention physical examination, we can strangle the cancer Voldemort in the bud at the beginning.
How to do cancer prevention physical examination?
According to the recommendations of the American Cancer Society (ACS) in 2015, with the increase of age, we should do these tests well:
Breast cancer (female)
20-30 years old (female)
-
Breast physical examination (once every 3 years)
40 years and over (female)
- Breast physical examination (once a year) mammography examination (once a year)
Colorectal cancer
50 years and over (all population)
Imaging examination (optional)
Every 5 years
- CT image of colon by barium enema
Every 10 years
-
Total colonoscopy
Laboratory examination (once every 1 year)
-
Fecal occult blood test
If any of the above results is positive, colonoscopy needs to be completed to determine the reason. If conditions permit, colonoscopy should be selected regardless of the results of fecal occult blood test.
Cervical cancer (female)
- 21 ~ 29 years old (female): cervical smear (once every 3 years), if the result is abnormal, HPV test will be considered; 30 ~ 65 years old (female): cervical smear examination and HPV examination are preferred (once every 5 years), and cervical smear examination can also be performed only (once every 3 years); Over 65 years old (female): If cervical cancer examination is carried out regularly and the results are normal, the examination can be stopped at this age. However, if precancerous lesions of cervical cancer, i.e. Severe cervical intraepithelial neoplasia, have been suffered from before, no matter whether they are over 65 years old or not, regular cervical cancer examination should be carried out for 20 years from the date of diagnosis of the disease. Women who are not related to cervical cancer but have had their uterus and cervix removed: if they have no history of tumor and no precancerous lesions in the cervix, cervical cancer screening can no longer be carried out; Women who have been vaccinated against HPV: The screening method is consistent with that of women who have not been vaccinated.
If you have been infected with HIV or have undergone organ transplantation, you must inform the doctor of your personal medical history so as to formulate an individualized examination plan.
Endometrial cancer (female)
Women who are already menopausal should be alert to the risk of endometrial cancer.
If there is vaginal bleeding of unknown causes and new spots on the body, the doctor should be informed in time.
For patients with a history of gynecological diseases in the past, doctors may advise her to complete an endometrial biopsy once a year (i.e. A very small amount of endometrial tissue is taken from the endometrium to observe whether there is any pathological change).
Lung cancer
Since the risk of lung cancer may be different for everyone even at the same age, here are only suggestions for health examination for those who are most likely to develop lung cancer, such as long-term smoking:
- 55-74 years old; In good health; 30 packs of smoking history, and smoking or quitting smoking for less than 15 years.
Package year refers to the number of packages that smoke every day multiplied by the number of years that smoke. For example, 30 package years can be two situations: smoking 3 packages a day for 10 years (3 × 10), or smoking 2 packages a day for 10 years, then changing to smoking 1 package a day for 10 years (2 × 10 + 1 × 10).
For those who meet these three characteristics, low-dose chest CT is recommended for lung cancer screening.
Prostate cancer
As the development of prostate cancer is relatively slow compared with other cancers, and the false positive rate of prostate cancer screening is too high, the examination results not only easily make the screening fall into the risk of [over-diagnosis], but also make patients bear psychological burden. Therefore, there is still controversy in medicine as to whether prostate should be included in cancer screening.
The American Cancer Society recommends that for men over 50, the patient should decide whether to undergo the prostate cancer examination after being fully informed of the advantages and disadvantages of the prostate cancer examination. If the family has a history of prostate cancer, the age should be advanced to 45 years old.
Never think that physical examination is a matter for the middle-aged and the elderly. The American Cancer Society recommends that adults over the age of 20 should have a routine physical examination once a year. Routine physical examination includes physical examination items related to cancer, such as thyroid gland, oral cavity, lymph nodes and abdomen. Specifically, doctors use their eyes and hands to judge whether there are abnormalities (such as hard lumps on thyroid gland and space occupying lumps in abdomen).
Those who have passed away cannot remonstrate, but those who have come can still be pursued. May the dead rest in peace and hope that through everyone’s efforts, cancer will no longer wreak havoc on the world.
