Cancer usually begins with one tumor in a specific area of the body. But if the tumor is not removed, cancer has the ability to spread to nearby organs as well as places far away from the origin, like the brain. How does cancer move to these new areas and why are some organs more likely to get infected than others? Ivan Seah Yu Jun explains the three common routes of metastasis.

Dr. Ebraheim’s educational animated video illustrates injection methods of the Gluteal region or the buttock.
Gluteal injection, buttock injection or Glute injection is common but it can injure the sciatic nerve.
INTRAMUSCULAR INJECTION OF THE BUTTOCK SHOULD BE SAFE.
Glute (buttock) injection is a universal procedure that is commonly used around the world.
The injection has to be safe.
Selecting the proper site that avoids injury to the neurovascular structures is important.
The sciatic nerve could be at risk for the injury during buttock injection.
Buttock is divided into quadrants.
Divide the buttock halfway down the middle and halfway across.
Injection is given in the center of the upper, outer quadrant.
Injection into the other quadrants may cause injury to the neurovascular structures.
Another helpful method could confirm a safe site for injection is to draw a line from the posterior superior edge of the iliac spine to the greater trochanter.
The area above the line is considered to be the safe zone for intramuscular injection.
This corresponds with the upper outer quadrant of the buttock and is the exact safe site for the buttock injection.

Cervical cancer is diagnosed usually in a gynecologist office and the usual course of events where cervical cancer is diagnosed, it is usually picked up on a screen Pap smear which shows an abnormality which then results in examination by gynecologist called colposcopy wherein an examination in their office is performed where with binocular microscopy, we evaluate the cervix and take directed biopsies of abnormalities that we observe. These biopsies are then looked at by a pathologist under microscope and then render a diagnosis as cervical dysplasia otherwise known as the precancer or precursor lesions of cervical cancer. Sometimes unfortunately is diagnosed as an invasive cervical cancer and when we see that the examination done by the physician is really the first and most important means of dictating how we take care of a patient. Cervical cancer still staged basically by an exam which is observation of the cervix, palpation or a physical exam of the cervix may help that the cancer is just as involve other adjacent structures and then we do use some radiologies such as CT scans, chest x-rays, etc., to help us guide how we take care of the patient and manage such cervical cancer.
Cervical cancer when we catch it in its early stages, stage 1 and sound specific stage 2s, we tend to use surgery for those treatments and that can be anything from a conservative operation meaning where the uterus is left in place such as what is called a conization where we excise the abnormality only on the cervix and leave the remaining cervix and leave the uterus in place. There are other options for that which is called a trachelectomy which is a procedure where the surgeon removes the cervix but leaves the uterus and we use that treatment modality in patients that have invasive cervical cancer that desire a future fertility. Furthermore, as we get into more advanced stages or in patients that fertility is not desired, a hysterectomy is performed and based upon complicated issues with regards to what the stage is and the cell type, sometimes a traditional what we call a simple hysterectomy is performed which is one that a general OB/GYN performs. However as the stage becomes more progressed what is called a radical hysterectomy is required and that is performed by a gynecologic oncologist.
In a radical hysterectomy is removal of the uterus and cervix in some of the adjacent structures called the parametrium. We also remove the lymph nodes at the time of that surgery to help dictate whether what is called adjuvant treatment is required and for some patients, depending upon certain issues on the pathologic specimen, chemotherapy and/or radiation maybe required depending upon certain pathologic events. As the stage gets more advanced such as certain stage 2 cancers even certain stage 1 cancers require radiation meaning that a hysterectomy is not the best first treatment. There are a lot of patients with cervical cancer that we do recommend radiation in lieu of hysterectomy because we know that the radiation is going to work as effective with less complications and the way that radiation is prescribed for patients with cervical cancers, we do use a combination of a very small dose of chemotherapy in conjunction with radiation. The chemotherapy is not a chemotherapy where patients lose their hair, no one will really know you are receiving the chemotherapy because it is such a small dose. That small dose of chemotherapy has actually been shown to help the radiation work better more effectively and cure more patients but the radiation is really the curative treatment for certain types of cervical cancer. That’s administered by a radiation oncologist, who is a doctor that treats cancer with radiation and they work in concert with the GYN oncologist with the chemotherapy. That course of treatment usually take somewhere between seven to eight weeks depending upon certain pathologic and radiologic findings. There is a combination of what is called external beam radiation where a patient lies on a table and the radiation comes just like if you are receiving an x-ray and then there is also a portion of what we call internal or Reiki therapy radiation which is one the radiation oncologist puts the radiation right on the cervix.

Have you ever considered just how amazing the human body really is? Some of the most remarkable discoveries in science take place within the human body, and while Some of these facts may be hard to believe, many of them will be happening inside of you right now!
The Human Brain Produces Enough Electricity To Power A Small Light Bulb. The image of a light bulb popping up above your head when you have that “eureka” moment isn’t too far off the mark, considering our brain’s use approximately as much energy as a 20 watt light bulb, it’s remarkable how efficient it is when compared to one the worlds fastest supercomputers that needed 82,000 processors and 40 minutes, to simulate just 1 second of just 1% of our brain activity.
Nails And Hair Do Not Continue To Grow After We Die. They do appear longer when we die, but It’s not that the fingernails and hair are growing, but that the skin around them has dehydrated, the skin dries out and retracts which makes the hair and nails appear longer.
The Pink Thing In The Inside Corner Of Your Eye Is Called The Plica Semilunaris And Is An evolutionary Leftover. The plica semilunaris is a remnant of a nictitating membrane, more commonly known as a third eyelid. It would have moved across the eye horizontally to protect, moisten and wipe away debris while maintaining visibility. Many fish, birds, reptiles and even some mammals like camels and polar bears have a third eye lid.
Facial Hair Grows Faster Than Any Other Hair On The Human Body. If the average man did not shave his facial hair during his entire life, it would grow to over 30 feet
,which is about the same length as double-decker bus.
Babies Are Born With 300 Bones But By Adulthood The Number Is Reduced To 206. The reason for this is that many of the bones of children are comprised of smaller component bones that are not yet fused like those in the skull, this makes it easier for a baby to pass through the birth canal, the bones then harden and fuse as the child grows.
Your Heart Beats About 100,000 Times A Day. During the average persons lifespan, the human heart will beat more than 2.5 billion times, that’s around 35 million times in just one year, so about 100,000 times a day.
Human Bones Ounce For Ounce Are Stronger Than Steel. A cubic inch of bone can in principle bear a load roughly the equivalent of five pickup trucks. The strongest bone
in the body is the femur or thighbone, which is about 48cm long. Our bones can also be made stronger, the impact of your feet hitting ground when running or the shock waves that are sent up your arm when punching a punch bag, create microscopic fractures that not only do your bones fix but also build extra bone on top off.
From The Age Of Thirty Humans Gradually Begin To Shrink In Size. Research has shown that by age 70, on average, men have become around an inch shorter and women around 2 inches shorter, with another inch lost by 80. This is because the discs between our vertebrates are compressed over time, also with age we become less efficient at replacing bone so our bones can also lose size and density.
The Surface Area Of A Human Lung Is Equal To A Tennis Court. In order to more efficiently oxygenate the blood, the lungs are filled with thousands of branching bronchi, filled with microscopic capillaries which convert oxygen to carbon dioxide. The large surface area makes it easier for this exchange to take place, and makes sure you stay properly oxygenated at all times.
If Uncoiled The DNA In All Of The Cells In Your Body Would Stretch 10 Billion Miles, From Here To Pluto And Back. DNA is a fine, spirally coiled thread in the nucleus ofevery living cell that serves as a guidebook so the cells know what they’re supposed to do. If you stretched the DNA in one cell all the way out,it would be about 2 metres long.
