Most women with breast cancer who undergo lumpectomy or partial mastectomy also undergo a course of radiation delivered to the whole of the affected breast.
While such treatment – called external beam radiotherapy, EBRT – reduces the risk of cancer coming back, it is not an easy undertaking and can cause unpleasant side effects. It takes weeks and requires regular attendance at centers that are not always easy to get to.
In the TARGIT-A trial, a large international team of researchers compared TARGIT with a standard EBRT course. The TARGIT method used a miniature X-ray machine to deliver targeted radiation to the tumor site once only during lumpectomy or about a month later, while the EBRT course comprised daily doses of radiotherapy for between 3 and 6 weeks.
In my point of view, not all of the breast cancer patient can benefit from TARGIT method since some of the cancer cell may already been transfer to other organs. But still, for the early treatment, the patient can assure that they will not have a chance to suffer from cancer again.

Can you imagine there is a device can control the taste of the food? Taste is a instinctive ability of human. Taste is the sensation produced when a substance in the mouth reacts chemically with receptors of taste buds.
Created by a team of researchers from the National University of Singapore and led by Nimesha Ranasinghe, the device – called the Tongue Mounted Digital Taste Interface – can transmit the taste elements through two silver electrodes once it touches the tip of the tongue. By manipulating magnitude, frequency and polarity of the silver electrode. So it can generate a signal to brain that the food taste good!
There are two main health benefits:
1. People with diabetes could use the device to stimulate sweet sensations without harming their blood sugar levels.
2. Cancer patients could use it to improve or regenerate their sense of taste – something that can be severely impaired by chemotherapy.
It makes patient can even taste good when they are not able to eat sweet food. And it has potential to heal the patient who got Anorexia Nervosa.

A hearing aid is an electroacoustic device which is designed to amplify sound for the wearer, usually with the aim of making speech more intelligible, and to correct impaired hearing as measured by audiometry.
However normal hearing aid can only allow patient to hear a little bit more. Most of them just relies on lip lancet in order to communicate with others.
Miller Reese Hutchinson of New York patented the first portable electric hearing aid. Called the “acousticon,” the device was a smaller version of previous tabletop units. While portable, it still had three components and used batteries that only lasted for a few hours. But it was far superior to ungainly hearing trumpets or simply cupping a hand behind the ear.
The unsolvable problem is to recharge the electric hearing aid after few hours of usage. Therefore, scientists must explore for tiny-but-high-capacity battery so patient who got hearing problem can benefit.

Some of the patient are suffering from paralyzing. There are multiple degree of paralysis as they have different part of spinal cord having injuries. For people who have whole body paralysed , they are unable to travel around but only stay on the bed for entire life in old days.
Nowadays, body piercings have been used to control wheelchairs and computers in a move scientists believe could transform the way people interact with the world after paralysis. The movement of a tiny magnet in a tongue piercing is detected by sensors and converted into commands, which can control a range of devices.
Spinal cord injury may not affect the tongue controlling because tetraplegic has its own hotline to the brain. A lentil-sized piercing in the tongue produces a magnetic field, which changes as the tongue moves. Sensors on the cheeks can then detect the precise position of the piercing. Thereby, the device can response to the tongue position to move the wheelchair.
This is a amazing invention that aloud the patient to go around after paralysis. Patient who can only stay on the bed for the entire live would be frustrating and despairing as they cannot feel the world outside the ward. Using the device to detect the tongue location can also functioning to control the television to switch the channel, typing. It can surely make their life much more better.
Hereby are the video shows how the pierced tongue work on wheelchair.
