There are many people who like to compare the so-called cancer manifestations, for example, it is said on the Internet that bowel cancer will cause blood in the stool, and some people find that they have blood in the stool recently, will it be bowel cancer?
If the diagnosis can be confirmed according to this control, I am afraid that everyone will get cancer.
Does that mean that some of the usual symptoms and manifestations of cancer are of no value at all? We don't need to pay attention to the symptoms anymore? Definitely not! The symptoms can be used as a reference to remind us to seek medical attention in time when necessary. In particular, some diseases and cancers have relatively obvious specific symptoms, that is, if these symptoms appear, they often strongly point to a certain disease and cancer, and this kind of disease must really be taken seriously.
I once saw a patient who developed blurred vision six months before the diagnosis. The patient is just 50 years old, which is not yet the age of presbyopia, and the sudden blurred vision is not normal.
But the patient didn't take it seriously, thinking that he had presbyopia. It is not until the symptoms get worse that the patient remembers to go for a full examination. This examination was unsuccessful, and he was directly diagnosed with brain cancer, and it has entered an advanced stage.
Everyone knows what it means to be at an advanced stage, especially for a malignant tumor like brain cancer, which means that the possibility of life is almost lost.
It is said that the eye is the window of the soul, but it is also the earliest manifestation of certain diseases. Although cancer catches people off guard, mastering some medical knowledge may be able to help us predict the disease in advance and avoid tragedy through some clues in the eyes.
For example, if the following 6 abnormalities appear in the eyes, it is likely to be a bad sign, and it is recommended to get checked as soon as possible!
(1) The whites of the eyes are yellowish
Yellowing of the whites of the eyes may be a sign of abnormal liver function, usually the bilirubin in the bile secreted by the liver will be metabolized, but once the liver function is abnormal, bilirubin may accumulate in the body, resulting in yellowing of the whites of the eyes.
In particular, the yellowing of the whites of the eyes is accompanied by dry and itchy eyes, which must be paid attention to, because this is likely to be a sign of early liver cancer.
In addition, bile duct cancer can cause abnormal bile secretion and affect the discharge of the eyes, so it is necessary to suspect the possibility of bile duct cancer if the eyes are dry and itchy.
(2) Protosis
When seeing proptosis of the eyeball, the first thing that comes to many people's minds is hyperthyroidism, which is commonly known as hyperthyroidism. In fact, some eye diseases and orbital tumors, among others, can cause proptosis.
For example, orbital striated muscles, orbital teratomas, etc., may cause proptosis of the eyeball, and some patients with nasopharyngeal carcinoma will also cause proptosis when cancer cells invade the orbital structure.
There are other cancers, such as lung, breast and melanoma, which can also cause proptosis due to metastasis to the orbit.
It is important to note that this is only a possibility, and does not necessarily mean that proptosis is associated with cancer. I just want to remind everyone that if there is an unexplained proptosis and it is accompanied by other eye symptoms, you must pay attention to it and seek medical attention in time.
(3) Rapid loss of vision
If there is rapid loss of vision in a short period of time, the first thing to be aware of is acute stroke, and the second thing to consider is that certain cancers, such as brain cancer and lung cancer, may affect the optic nerve, which can lead to sudden blurring of vision. In addition, optic nerve malignancies and neuroblastoma can also cause rapid vision loss.
(4) "Moles" in the eyes
A "mole" has grown on the inside of the eye, most likely a sign of a conjunctival pigmented nevus. As a benign melanoproliferative lesion, conjunctival pigmented nevi typically appear in childhood.
Conjunctival pigmented nevi generally do not change, and only a few may change over time. The proportion of conjunctival pigmented nevus cancer turning into melanoma is less than 1%, although the proportion is very low, but if it is found that the conjunctival pigmented nevus grows too fast, and there are uneven objects on the pigmented surface, it is still necessary to be alert to the occurrence of cancer.
(5) Drooping eyelids
Ptosis may be an early sign of lung cancer, because when lung cancer invades the thoracic nerve, recurrent laryngeal nerve or phrenic nerve, the nerve is compressed or destroyed, resulting in nerve signaling blockage, which affects the movement of the muscles that control the lifting of the eyelids, and eventually leads to ptosis.
Of course, we can't equate drooping eyelids with lung cancer, but lung cancer is one of the diseases that can cause drooping eyelids, excluding the diseases of the eye itself.
(6) Visual field defects
Brain tumors are the first thing to consider after visual field defects, as they can compress or erode visual pathways, such as the optic nerve and visual cortex, resulting in visual field defects.
In addition, optic nerve malignancies and craniopharyngiomas, etc., will have a serious impact on vision, resulting in visual field defects.
Of course, there are many causes of visual field defects, and it does not mean that the appearance of visual field defects is necessarily related to cancer. For example, glaucoma, acute stroke, and retinal diseases can all cause visual field defects.
Finally, I would like to remind you that the above symptoms are only for reference, not absolute, and should not be caused by anxiety. However, if the above symptoms appear frequently in the eyes, or suddenly and unexplained symptoms, and the symptoms do not disappear for a long time, or even become more severe, it must be taken seriously.
